    5 Description (continued)The six-channel, 24-bit analog-to-digital converter (ADC) employs a delta-sigma () modulator and supports8-kHz to 96-kHz sampling 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 modulator and supports 8-kHz to192-kHz sampling rates and a 16-bit/24-bit width digital audio input word on the audio interface. Each audiointerface supports I2S, left-justified, right-justified, and DSP formats with 16-bit/24-bit word width. In addition, thePCM3168A device supports the time-division-multiplexed (TDM) format.

    The PCM3168A device 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, softmute, de-emphasis, and so forth. Also, hardware control mode provides a subset of user-programmablefunctions through four control pins. The PCM3168A device is available in a 12-mm 12-mm (10-mm 10-mmbody) HTQFP-64 PowerPAD package.
