CS4351

112 dB, 24-Bit, 192 kHz Stereo D/A Converter with Line Driver

Overview

Description

The CS4351 is a complete stereo digital-to-analog (D/A) system including digital interpolation, fifth-order multibit Delta-Sigma D/A conversion, digital de-emphasis, volume control, channel mixing, analog filtering and integrated line-level driver.

The advantages of this architecture include: ideal differential linearity; no distortion mechanisms due to resistor matching errors; no linearity drift over time and temperature; high tolerance to clock jitter; and premium sound quality.

The CS4351 requires a minimal set of external components and therefore minimizes board space requirements, reduces system cost and is easy to use. Accepting digital audio data at sample rates from 4 kHz to 192 kHz, the CS4351 is ideal for a wide range of audio systems including DVD players and recorders, digital set-top boxes, digital televisions, mini-component systems and audio/video receivers.
