Feature List
● 24-bit Sigma- Delta ADC and DAC
● Allows 2Vrms input swing into ADC part
● ADC up to 96 kHz sampling rates
● 90 dB ADC dynamic range
● Automatic Gain Control (AGC)
● 90 dB DAC dynamic range
● DAC up to 192 kHz sampling rates
● Two channels of ADC and four independent channels of DACs (two L/R line outputs and a
headphone output)
● Supports two sets of I2S clocks and data inputs independently
● System clocks: 128Fs, 192Fs, 256Fs, 384Fs, 512Fs, 768Fs
● Selectable serial audio interface formats:left justified, right justified and I2S up to 24 bits
● +3.0V to +3.6V digital power supply
● +8.2V to +13.2V analog power supply
● 7-channel input multiplexer with ADC programmable gain amplifier's (PGA's) gain from +21dB
to –21dB in 0.5dB step
● Two individual sets of I2S ports simultaneously support different sample rates for the ADC and
DACs and then output from DAC1 and DAC2 independently
