资 源 简 介
The PCM1691 is a high-performance, single-chip, 24-bit, eight-channel, audio digital-to-analog converter (DAC) with single-ended outputs. The eight-channel, 24-bit DAC employs an enhanced mulTI-level, delta-sigma () 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 PCM1691 audio interface supports a TIme-division-mulTIplexed (TDM) format in addiTIon to I2S, left-justified, right-justified, and DSP formats.
The PCM1691 can be controlled through a three-wire, SPI-compatible or two-wire, I2C-compatible serial interface in software, which provides access to all functions including digital attenuation, soft mute, de-emphasis, and so forth.
