The PCM3168A device is a high-performance, single-chip, 24-bit, 6-in/8-out, audio coder and decoder (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 (ΔΣ) modulator and supports 8-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 ΔΣ modulator and supports 8-kHz to 192-kHz sampling rates and 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 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, soft mute, de-emphasis, and so forth. Also, hardware control mode provides a subset of user-programmable functions through four control pins. The PCM3168A device is available in a 12-mm × 12-mm (10-mm × 10-mm body) HTQFP-64 PowerPAD™ package.
