24-Bit, 192 kHz, Stereo D/A Converter with Volume Control

The CS4392 is a complete, stereo, digital-to-analog system including digital interpolation, fifth-order Delta-Sigma digital-to-analog conversion, digital de-emphasis, volume control, channel mixing, and analog filtering. The advantages of this architecture include: ideal differential linearity, no distortion mechanisms due to resistor matching errors, no linearity drift over time and temperature, and a high tolerance to clock jitter.

The CS4392 accepts PCM data at sample rates from 4 kHz to 192 kHz and DSD audio data, has selectable digital filters, and consumes very little power. These features are ideal for DVD, SACD players, A/V receivers, CD, and set-top box systems. The CS4392 is pin and register compatible with the CS4391 making easy performance upgrades possible.
