Digital Volume Control
Each DAC’s output level is controlled via the Volume Control registers operating over the range of 0 to
-127.5 dB attenuation with 0.5 dB resolution. See

maximum value (-127.5 dB). When the AOUTx_MUTE bit is disabled, the corresponding DAC returns to
the attenuation level set in the Volume Control register. The attenuation is ramped up and down at the
rate specified by the SZC[1:0] bits.
De-Emphasis Filter
The CS42436 includes on-chip digital de-emphasis optimized for a sample rate of 44.1 kHz. The filter re-
