CS4340A

24-Bit, 192 kHz Stereo DAC for Audio

Features

101

Description

The CS4340A is a complete stereo digital-to-analog sys-

tem including digital interpolation, fourth-order delta-

sigma digital-to-analog 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 CS4340A accepts data at all standard audio sample

rates up to 192 kHz, consumes very little power, oper-

ates over a wide power supply range and is pin

compatible with the CS4340, as described in section 3.1.

These features are ideal for DVD audio players.
