This PCM3060 is a low-cost, high-performance, single-chip, 24-bit stereo single-ended analog input and differential analog output audio codec.

The stereo 24-bit ADC uses a 64x Δ-Σ modulator. It supports sampling rates from 16 to 96 kHz and audio output words on 16/24-bit digital audio interfaces.

The stereo 24-bit DAC uses a 64- or 128x Δ-Σ modulator. It supports sampling rates from 16 to 192 kHz and audio input words on 16/24-bit digital audio interfaces.

Supported PCM3060 ADC and DAC operate completely independently for sampling rate and audio interfaces.

Each audio interface supports I2, left-aligned, with text and formats aligned to 16/24-bit right.

The PCM3060 can be controlled via software via a 3-wire SPI-compatible or 2-wire I2C-compatible serial interface, providing access to all functions, including digital attenuation, soft mute, de-emphasis, and more
