input path. The PGAxSEL bits may be used to isolate the input signal(s) from the PGA outputs. When

the PGA is powered down, no input should be selected. Refer to “ADC Input Select” on page 48 and

“PGA Input Mapping” on page 49 for the required settings.

6.2.3

Power Down ADCx

Configures the power state of ADC channel x.

Notes:

The CS42L52 employs a clever scheme for controlling the power to the ADC when PASSTHRU

(“Passthrough Analog” on page 52) and PDN_OVRD (“Power Down ADC Override” on page 43) are

enabled. Refer to the referenced application.

6.2.4

Power Down

Configures the power state of the entire CODEC.

6.3

Power Control 2 (Address 03h)

6.3.1

Power Down ADC Override

Configures an override of the power down control for ADCx.

6.3.2

Power Down MICx

Configures the power state of the microphone pre-amplifier for channel x.

6.3.3

Power Down MIC Bias

Configures the power state of the microphone bias circuit.
