Low-Voltage, Dual SPDT, Audio Clickless
Switches with Negative Rail Capability
General Description
Features
♦ Distortion-Free Negative Signal Throughput Down
The MAX4762–MAX4765 dual SPDT (single-pole/double-
throw) switches feature negative 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-resis-
tance, making them ideal for switching audio signals.

♦ Comparator for Headphone or Mute Detection
(MAX4763/MAX4765)
♦ Internal Shunt Resistor Reduces Click/Pop
The MAX4763/MAX4765 include a comparator that can
be used for headphone detection or a mute/send key
function. The MAX4764/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.
(MAX4764/MAX4765)
♦ 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)
♦ -65dB Off-Isolation (100kHz)
♦ 0.01% Total Harmonic Distortion
These SPDT switches are available in space-saving
™
µMAX, TDFN, thin QFN, and UCSP packages and oper-
ate over the -40°C to +85°C extended temperature range.

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.

Analog Signal Levels
The on-resistance of the MAX4762–MAX4765 changes
very little for analog input signals across the entire supply
voltage range (see the Typical Operating Characteristics).
The switches are bidirectional, so the NO_, NC_, and

Shunt Switch (MAX4764/MAX4765)
The 100Ω shunt switches on the MAX4764/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–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 nomi-
nal 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.
Power-Supply Sequencing and
Overvoltage Protection
Caution: Do not exceed the absolute maximum ratings
since stresses beyond the listed ratings may cause
permanent damage to the device.
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/MAX4765 feature an internal shunt
CC
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.
Proper power-supply sequencing is recommended for
all CMOS devices. Always apply V
before applying
CC
analog signals, especially if the analog signal is not
current-limited.
Applications Information
UCSP Applications Information
Digital Control Inputs
The MAX4762–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).
For the latest application details on UCSP construction,
dimensions, tape carrier information, printed circuit board
techniques, bump-pad layout, and recommended reflow
temperature profile, as well as the latest information on
reliability testing results, go to the Maxim’s website at
