4.5 Analog Output Volume Tab

The “Analog Output Volume” tab provides high-level control of the CS42L55 Class H output amplifier,

HP/Line output volume levels, charge pump frequency and overall master volume level. This tab also pro-

vides control functions for the DAC channel limiter. Status text detailing the CODEC’s specific configuration

is shown in read-only edit boxes. This text will change depending on the setting of the associated control.

A description of each control group is outlined below (register descriptions are in the CS42L55 data sheet).

Class H Controls - Controls for defining the digital and analog advisory volume, charge pump frequency and

adaptive power supply mode for the Class H amplifier.

the headphone/line amplifier. Also allows one to configure the HP/Line mux to choose if the input signal to

the HP/Line amplifiers comes from the DAC or the PGA.
