Description

The CS4340 is a comple te stereo digita l-to-analog s ystem including digital interpolation, fourth-order deltasigma digital-to- analog conversion, dig ital de-emphasis and switched capacitor analog filtering. The advantages of this architecture include: id eal diffe rential li nearity , no distortion mechanis ms due to resistor matching errors , no linearity drift over tim e and temperature and a high tolerance to clock jitter.

The CS4340 accepts data at audio sa mple 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 box and automotive systems.
