Low-Voltage, Dual SPDT, Audio Clickless
Switches with Negative Rail Capability
General Description
Features
♦ Distortion-Free Negative Signal Throughput Down
The MAX4762–MAX4764/MAX4764A/MAX4765 dual
SPDT (single-pole/double-throw) switches feature nega-
tive signal capability that allows signals below ground to
pass through without distortion. These analog switches
operate from a single +1.8V to +5.5V supply and have
low 0.6Ω on-resistance, making them ideal for switching
audio signals.

♦ Comparator for Headphone or Mute Detection
(MAX4763/MAX4765)
♦ Internal Shunt Resistor Reduces Click/Pop
(MAX4764/MAX4764A/MAX4765)
The MAX4763/MAX4765 include a comparator that can
be used for headphone detection or a mute/send key
function. The MAX4764/MAX4764A/MAX4765 have an
internal shunt switch to automatically discharge any
capacitance at the NO and NC connection points. This
reduces click-and-pop sounds that occur when switching
audio signals between precharged points.
♦ Low On-Resistance (R
)
ON
0.6Ω at +2.7V Supply
♦ 0.25Ω On-Resistance Flatness
♦ 0.05Ω On-Resistance Matching
♦ +1.8V to +5.5V Supply Voltage
♦ -70dB Crosstalk (100kHz)
These SPDT switches are available in space-saving
®
™
µMAX , TDFN, thin QFN, and UCSP packages and
operate over the -40°C to +85°C extended tempera-
ture range.
♦ -65dB Off-Isolation (100kHz)
♦ 0.01% Total Harmonic Distortion
Applications
♦ Available in µMAX, TDFN, Thin QFN, and UCSP

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Switches with Negative Rail Capability
Analog Signal Levels
The on-resistance of the MAX4762–MAX4764/
MAX4764A/MAX4765 changes very little for analog input
signals across the entire supply voltage range (see the
Typical Operating Characteristics). The switches are bidi-
rectional, so the NO_, NC_, and COM_ pins can be either
inputs or outputs.

(MAX4764/MAX4764A/MAX4765)
The 100Ω shunt switches on the MAX4764/MAX4764A/
MAX4765 automatically discharge any capacitance at
the NC_ or NO_ terminals when they are unconnected
to COM_. This reduces audible click-and-pop sounds
that occur when switching between audio sources.
Figure 1. Typical Operating Circuit
Detailed Description
The MAX4762–MAX4764/MAX4764A/MAX4765 are low
on-resistance, low-voltage, dual SPDT analog switches
that operate from a +1.8V to +5.5V supply and are fully
specified for nominal 3.0V applications. The devices
feature a negative signal capability that allows signals
below ground to pass through without distortion and
have break-before-make switching.
Audible clicks and pops are caused when a step DC
voltage is switched into the speaker. By automatically
discharging the side that is not connected, any residual
DC voltage is removed, thereby reducing the clicks
and pops.
The MAX4763/MAX4765 feature a comparator that can be
used for headphone or mute detection. The comparator
threshold is internally generated to be approximately 1/3

of V . The MAX4764/MAX4764A/MAX4765 feature an
CC
internal shunt switch to discharge any capacitance at the
NO and NC connection points. This reduces the click-
and-pop sounds that occur when switching audio signals.

Applications Information
analog signals, especially if the analog signal is not
current-limited.
Digital Control Inputs
The MAX4762–MAX4764/MAX4764A/MAX4765 logic
inputs accept up to +5.5V, regardless of supply voltage.
For example, with a +3.3V supply, IN_ can be driven low
to GND and high to +5.5V allowing for mixing of logic
levels in a system. Driving IN_ rail-to-rail minimizes
power consumption. For a +1.8V supply voltage, the
logic thresholds are 0.5V (low) and 1.4V (high); for a
+5V supply voltage, the logic thresholds are 0.8V (low)
and 2.0V (high).
