Low-Voltage, Dual SPDT, Audio Clickless Switches with Negative Rail Capability
General DescriptionThe 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 0.6Ωon-resistance, making them ideal for switching
audio signals.
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.
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.

MAX4762–MAX4764/MAX4764A/MAX4765
Detailed DescriptionThe 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.
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 VCC. The MAX4764/MAX4764A/MAX4765 feature an
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
Digital Control InputsThe 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-railminimizes
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).
Analog Signal LevelsThe on-resistance of the MAX4762–MAX4764/
MAX4764A/MAX4765changes 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.
The MAX4762–MAX4764/MAX4764A/MAX4765pass
signals as low as VCC- 5.5V, including signals below
ground with minimal distortion.
Comparator (MAX4763/MAX4765)The MAX4763/MAX4765 include a comparator that can
be used for mute and headphone detection functions.
The positive terminal of the comparator is internally set to
VCC / 3. When the negative terminal (CMP-) is below the
threshold, the comparator output (CMPO) is a logic high.
When CMP- rises above VCC / 3, CMPO is a logic low.
The comparator threshold of VCC / 3 allows for detection
of headphones because headphone audio signals are
typically biased to VCC / 2.
Shunt Switch
(MAX4764/MAX4764A/MAX4765)The 100Ωshunt 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.
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.Proper power-supply sequencing is recommended for
all CMOS devices. Always apply VCCbefore applying
analog signals, especially if the analog signal is not
current-limited.
