HIGH-LEVEL OUTPUT CURRENT
The TLV2252 and TLV2254 are dual and
quadruple low-voltage operational amplifiers from
Texas Instruments. Both devices exhibit rail-to-rail
output performance for increased dynamic range
in single- or split-supply applications. The
TLV225x family consumes only 34 µA of supply
current per channel. This micropower operation
makes them good choices for battery-powered
applications. This family is fully characterized at
3 V and 5 V and is optimized for low-voltage
applications. The noise performance has been
dramatically improved over previous generations
of CMOS amplifiers. The TLV225x has a noise
level of 19 nV/√Hz at 1kHz, four times lower than
competitive micropower solutions.

The TLV225x, exhibiting high input impedance
and low noise, are excellent for small-signal
conditioning for high-impedance sources, such as
piezoelectric transducers. Because of the micro-
power dissipation levels combined with 3-V
operation, these devices work well in hand-held

monitoring and remote-sensing applications. In addition, the rail-to-rail output feature with single or split supplies
makes this family a great choice when interfacing with analog-to-digital converters (ADCs). For precision
applications, the TLV225xA family is available and has a maximum input offset voltage of 850 µV.
The TLV2252/4 also make great upgrades to the TLV2322/4 in standard designs. They offer increased output
dynamic range, lower noise voltage, and lower input offset voltage. This enhanced feature set allows them to
be used in a wider range of applications. For applications that require higher output drive and wider input voltage
range, see the TLV2432 and TLV2442 devices. If your design requires single amplifiers, please see the
TLV2211/21/31 family. These devices are single rail-to-rail operational amplifiers in the SOT-23 package. Their
small size and low power consumption, make them ideal for high density, battery-powered equipment.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

APPLICATION INFORMATION
driving large capacitive loads
The TLV2252 is designed to drive larger capacitive loads than most CMOS operational amplifiers. Figure 56
and Figure 57 illustrate its ability to drive loads up to 1000 pF while maintaining good gain and phase margins
(R
= 0).
null
A smaller series resistor (R ) at the output of the device (see Figure 60) improves the gain and phase margins
null
when driving large capacitive loads. Figure 55 and Figure 56 show the effects of adding series resistances of
10 Ω, 50 Ω, 100 Ω, 200 Ω, and 500 Ω. The addition of this series resistor has two effects: the first adds a zero
to the transfer function and the second reduces the frequency of the pole associated with the output load in the
transfer function.
The zero introduced to the transfer function is equal to the series resistance times the load capacitance. To
calculate the improvement in phase margin, equation 1 can be used.

The unity-gain bandwidth (UGBW) frequency decreases as the capacitive load increases (see Figure 58). To
use equation 1, UGBW must be approximated from Figure 58.
Using equation 1 alone overestimates the improvement in phase margin as illustrated in Figure 59. The
overestimation is caused by the decrease in the frequency of the pole associated with the load, providing
additional phase shift and reducing the overall improvement in phase margin.
Using Figure 60, with equation 1 enables the designer to choose the appropriate output series resistance to
optimize the design of circuits driving large capacitance loads.

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 JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. 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.
