The CXES4272 is a high-density, double-pole/ doublethrow (DPDT) analog switch which allows signals from - 0.3V to +5.5V to pass without distortion even when the power supply is below the signal range. The low RON resistance (0.2W) makes the devices ideal for low-distortion switching, such as audio. The CXES4272 has internal shunt switches that discharge the audio amplifier AC-coupling capacitance at the normally open (NO1 and NO2) terminals

The CXES4272 is a high-density, double-pole/ doublethrow (DPDT) analog switch which allows signals from - 0.3V to +5.5V to pass without distortion even when the power supply is below the signal range. The low RON resistance (0.2W) makes the devices ideal for low-distortion switching, such as audio. The CXES4272 has internal shunt switches that discharge the audio amplifier AC-coupling capacitance at the normally open (NO1 and NO2) terminals. This feature reduces click-and-pop sounds that occur when switching audio signals between precharged points. The switches are fully specified to operate from a single +2.9V to +5.5V power supply. Because of the low supply current requirement, VCC can be provided by a GPIO. When the power is not applied, switches go to a high-impedance mode and all analog signal ports can withstand signals from -0.3V to +5.5V. The devices control the switches with a control bit, CB. The CXES4272 is available in a 1.2mm x 1.2mm, 0.4mm pitch, 9-bump wafer-level package (WLCSP), and operate over the -4oC to +85oC extended temperature range.
