Analog Passthrough
The CS43L22 accommodates analog routing of the analog input signal directly to the headphone amplifiers
by using the PASSTHRUx mux. This feature is useful in applications that utilize an FM tuner where audio
recovered over-the-air must be transmitted to the headphone amplifier directly. This analog passthrough
path reduces power consumption and is immune to modulator switching noise that could interfere with some
tuners.
Four analog input channels can be chosen or summed by using the PASSxSEL bits as shown in Figure 8
to provide input to the CS43L22 when in analog passthrough mode. A pair of passthrough amplifiers can be
used to mute and apply gain to the input signals.
