Description
The PCM3168A and PCM3168A-Q1 are high-performance, single-chip, 24-bit, 6-in/8-out, audio coders/decoders(codecs) with single-ended and differential selectable analog inputs and differential outputs. The six-channel,24-bit analog-to-digital converter (ADC) employs a delta-sigma (?S) modulator and supports 8-kHz to 96-kHzsampling rates and a 16-bit/24-bit width digital audio output word on the audio interface. The eight-channel,24-bit digital-to-analog converter (DAC) employs a ?S modulator and supports 8-kHz to 192-kHz sampling ratesand a 16-bit/24-bit width digital audio input word on the audio interface. Each audio interface supports I2S,left-justified, right-justified, and DSP formats with 16-bit/24-bit word width. In addition, the PCM3168A andPCM3168A-Q1 support the time-division-multiplexed (TDM) format.The PCM3168A and PCM3168A-Q1 can be controlled through a four-wire, SPI-compatible interface, 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. Also, hardware control mode provides a subset of user-programmablefunctions through four control pins. The PCM3168A and PCM3168A-Q1 are available in a 12-mm × 12-mm (10-mm × 10-mm body) HTQFP-64 PowerPAD package.
