Two DAC outputs reach 2Vrms in a 12V supply environment including a headphone, two
left/right line outputs with volume gain/attenuation from -127 dB to +12 dB and digital
de-emphasis function. Sampled data is transmitted through the serial audio interface at
various rates from 32 KHz to 192 KHz. For audio clock applications, the MT8291E
supports master, slave modes and three data formats in the serial interface. Two individual

sets if I
S ports including three clocks and digital data for each simultaneously support
different sample rates for the ADC and DACs and then output from DAC1 and DAC2
independently.
