The analogue output from the DAC can then be mixed with the MIC2 analogue input and the ADC
analogue input. The mix is fed to the output drivers, SPKOUTP/N, and MONOOUT.
MONOOUT: can drive a 16Ω or 32Ω headphone or line output or can be a buffered version of VMID
(When MONOMUTE=1).
SPKOUTP/N: can drive a 16Ω or 32Ω stereo headphone or stereo line output, or an 8Ω BTL mono
speaker.
DIGITAL HI-FI DAC VOLUME CONTROL
The signal volume from each Hi-Fi DAC can be controlled digitally. The gain and attenuation range is
–127dB to 0dB in 0.5dB steps. The level of attenuation for an eight-bit code X is given by:
0.5 × (X-255) dB for 1 ≤ X ≤ 255;
Table 23 DAC Volume
HI-FI DIGITAL TO ANALOGUE CONVERTER (DAC)
Digital ‘de-emphasis’ can be applied to the audio data if necessary. De-emphasis filtering is available
for sample rates of 48kHz, 44.1kHz and 32kHz.
Table 24 De-Emphasis
The DAC is enabled by the DACEN register bit.
