APL3157 Description
The APL3157 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 (0.2Ω) makes the devices ideal for low-distortion switching, such as audio. The APL3157 has internal shunt switches that discharge the audio amplifier.
