DESCRIPON

The PCM1690-Q1 is a high-performance, single-chip, 24-bit, eight-channel, audio digital-to-analog converter DAC with differential outputs. The eight-channel, 24-bit DAC employs an enhanced, multi-level delta-sigma ΔΣ modulator and supports 8-kHz to 192-kHz sampling rates and a 16-/20-/24-/32-bit width digital audio input word on the audio interface. The audio interface of the PCM1690-Q1 supports the time-division-multiplexed TDM format in addition to the standard I2S, left-justified, right-justified, and DSP formats.
