ture high continuous current ratings of 550mA (continu-
ous) and 850mA (pulsed). These analog switches have
low on-resistance, low supply current, and operate from
a single +2.3V to +5.5V supply.
o Low On-Resistance 0.36Ω (typ)
o 1mΩ (typ) On-Resistance Flatness
o COM High Impedance for EN = High
The MAX14505/MAX14505A have internal shunt switches
that discharge the audio amplifier AC-coupling capaci-
tance at the normally open (NO) terminals. This reduces
click-and-pop sounds that occur when switching audio
signals between precharged points. The MAX14504/
MAX14505/MAX14505A/MAX14506 control the switches
with control bit, CB, and feature an enable input, EN, that
place COM in a high-impedance mode.
o Low 0.2µA (max) Shutdown Current
(MAX14505A/MAX14506)
o +2.3V to +5.5V Single-Supply Voltage
o Small, 1.56mm x 2.14mm, 12-Bump WLP Package
Pin Configuration
The MAX14504/MAX14505/MAX14505A/MAX14506 are
fully specified to operate from a single +2.3V to +5.5V
power supply. These devices are available in a 1.56mm
x 2.14mm, 12-bump WLP package, and operate 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.

and-pop sounds that occur when switching between
capacitively coupled audio sources. Audible clicks and
pops are caused when a step DC voltage is switched
into the speaker. The DC step transients are reduced
by automatically discharging the side that is not con-
nected to the COM terminal, reducing any residual DC
voltage and reducing clicks and pops.
Digital Control Inputs
The MAX14504/MAX14505/MAX14505A/MAX14506
logic inputs accept up to +5.5V, regardless of supply
voltage. For example, with a +3.3V supply, CB and EN
can be driven low to GND and high to +5.5V, allowing
for mixed logic levels in a system. Using logic levels of
V
= 0 to V ≥ V
reduces supply current.

Applications Information
Analog Signal Levels
These devices pass signals from -V to +V with
minimal distortion and very little change in on-resistance
(see the Typical Operating Characteristics). The switch-
es are bidirectional; therefore, the NO_, NC_, and COM_
terminals can be used as either inputs or outputs.

Power-Supply Sequencing
Proper power-supply sequencing is recommended for
all CMOS devices. Improper supply sequencing can
force the switch into latch-up, causing it to draw exces-
sive supply current. The only way out of latch-up is to
remove all signals and power and then reapply properly.
Connect all ground pins first, apply power to V , and
CC
finally apply signals to NO_, NC_, and COM_. Follow the
reverse order upon power-down.
Click-and-Pop Suppression
The MAX14505/MAX14505A have a shunt switch on
NO1 and NO2 terminals to automatically discharge any
capacitance when they are not connected to COM1
and COM2. The shunt switch reduces audible click-
