AUDIO
Channel Performance
The receive channel of TLV320DAC3202 converts the digital signal to analog for the headset amplifier through a
highly efficient low-power DAC. The signal in stereo I2S format with configurable data size drives the Class G
amplifier after the conversion. The channel gain is implemented in two segments in digital and analog domains.
In digital domain the gain steps have finer resolution whereas in the analog domain the amplifier gain steps are
defined at 2-dB resolution. The detail of volume control is shown in the register map description. The mixing
feature allows the left and right channels to be combined in digital domain prior to conversion and then routed to
either channel. The audio signal can be disabled either by soft mute feature in the digital domain or by disabling
the output amplifier.

Volume Control
The volume control module is implemented with combination of digital and analog gain settings for optimum
performance. The total gain range is from 4 dB to -59 dB with variable steps. The gain for the amplifiers is from 4
dB to -12 dB in 2-dB steps.
