CS4340

101 dB, 24-Bit, 96 kHz Stereo D/A Converter

Overview

Description

The CS4340 is a complete stereo digital-to-analog (D/A) system including digital interpolation, fourth-order Delta-Sigma D/A conversion, digital de-emphasis, and switched capacitor 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 CS4340 accepts data at audio sample rates from 2 kHz to 100 kHz, consumes very little power, and operates over a wide power supply range. The features of the CS4340 are ideal for DVD players, CD players, set-top boxes, and automotive systems.
