APPLICATION INFORMATION
LINE DRIVER AMPLIFIERS
Single-supply line-driver amplifiers typically require dc-blocking capacitors. The top drawing in Figure 9 illustrates
the conventional line-driver amplifier connection to the load and output signal.
DC blocking capacitors are often large in value, and a mute circuit is needed during power up to minimize click
and pop. The output capacitor and mute circuit consume PCB area and increase cost of assembly, and can
reduce the fidelity of the audio output signal.

Figure 9. Conventional and DirectPath Line Driver
The DirectPath™ amplifier architecture operates from a single supply but makes use of an internal charge pump
to provide a negative voltage rail.
Combining the user-provided positive rail and the negative rail generated by the IC, the device operates in what
is effectively a split supply mode.
The output voltages are now centered at zero volts with the capability to swing to the positive rail or negative rail.
Combining this with the built-in click and pop reduction circuit, the DirectPath™ amplifier requires no output dc
blocking capacitors.
The bottom block diagram and waveform of Figure 9 illustrate the ground-referenced line-driver architecture. This
is the architecture of the TPA6139A2.

SLOS700B –JANUARY 2011–REVISED JUNE 2012

COMPONENT SELECTION
Charge Pump
The charge pump flying capacitor serves to transfer charge during the generation of the negative supply voltage.
The VSS capacitor must be at least equal to the charge pump capacitor in order to allow maximum charge
transfer. Low ESR capacitors are an ideal selection, and a value of 1μF is typical. Capacitor values that are
smaller than 1μF cannot be recommended as it limits the negative voltage swing in low impedance loads.
Decoupling Capacitors
The TPA6139A2 is a DirectPath™ amplifier that requires adequate power supply decoupling to ensure that the
noise and total harmonic distortion (THD) are low. A good low equivalent-series-resistance (ESR) ceramic
capacitor, typically 1μF, placed as close as possible to the device VDD leads works best. Placing this decoupling
capacitor close to the TPA6139A2 is important for the performance of the amplifier. For filtering lower frequency
noise signals, a 10-μF or greater capacitor placed near the audio power amplifier also helps, but it is not required
in most applications because of the high PSRR of this device.
Gain-Setting
The gain setting is programmed with the GAIN pin individually for line driver and headphone section. Gain setting
is latched when the MUTE pin is set high. Table 1 lists the gain settings. The default gain with the gain-set pin
left open is –2x.

Input-Blocking Capacitors
DC input-blocking capacitors are required to be added in series with the audio signal into the input pins of the
TPA6139A2. These capacitors block the dc portion of the audio source and allow the TPA6139A2 inputs to be
properly biased to provide maximum performance. The input blocking capacitors also limit the DC gain to 1,
limiting the DC-offset voltage at the output.
These capacitors form a high-pass filter with the input resistor, RIN. The cutoff frequency is calculated using
Equation 1. For this calculation, the capacitance used is the input-blocking capacitor and the resistance is the
input resistor chosen from Table 1. Then the frequency and/or capacitance can be determined when one of the
two values is given.

For a fixed cutoff frequency of 2Hz the size of the input capacitance is shown in the table below with the
capacitors rounded up to nearest E6 values. For 20Hz cutoff simply divide the capacitor values with 10; e.g., for
1x gain, 150nF is needed.

Pop-Free Power Up
Pop-free power up is ensured by keeping the MUTE low during power supply ramp up and down. The pin should
be kept low until the input AC-coupling capacitors are fully charged before asserting the MUTE pin high to pre-
charge the ac-coupling; and, pop-less power-up is achieved. Figure 10 illustrates the preferred sequence.

A proposed layout for the TPA6139A2 can be seen in the TPA6139A2EVM User's Guide (SLOU248), and the
Gerber files can be downloaded from http://focus.ti.com/docs/toolsw/folders/print/TPA6139A2evm.html. To
access this information, open the TPA6139A2 product folder and look in the Tools and Software folder.
Ground traces are recommended to be routed as a star ground to minimize hum interference. VDD, VSS
decoupling capacitors and the charge pump capacitors should be connected with short traces.
PIN COMPATIBLE WITH THE DRV612
The TPA6139A2 stereo Headphone amplifier is pin compatible with the DRV612 . A single PCB layout can
therefore be used with stuffing options for different board configurations.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46C and to discontinue any product or service per JESD48B. Buyers should
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All
semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time
of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which
have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such
components to meet such requirements.
