DESCRIPTION

The PCM3060 is a low-cost, high-performance,

single-chip, 24-bit stereo audio codec with

single-ended analog inputs and differential analog

outputs.

The stereo 24-bit ADC employs a 64-times

delta-sigma modulator. It supports 16–96 kHz sampling rates and a 16/24-bit digital audio output

word on the audio interface.

The stereo 24-bit DAC employs a 64- or 128-times

delta-sigma modulator. It supports 16–192 kHz

sampling rates and a 16/24-bit digital audio input

word on the audio interface.

The PCM3060 supports fully independent operation

of the sampling rate and audio interface for the ADC and DAC.

Each audio interface supports I2S, left-justified, and right-justified formats with 16/24-bit words.
