The CS4340A is a Delta-Sigma stereo digital-to-analog (D/A) converter that supports next-generation audio formats such as DVD-Audio — it is ideal for a wide range of consumer entertainment applications such as digital audio/video receivers, DVD recorders and players, and automotive audio systems. The CS4340A is a complete D/A system that includes digital interpolation, digital de-emphasis, and switched capacitor analog filtering.

The product's major advantages include ideal differential linearity; no distortion caused by resistor matching errors; no linearity drift over time and temperature; and a high tolerance to clock jitter. It supports all standard audio sample rates up to 192 kHz, consumes very little power, and operates over a wide power supply range.

With 101 dB dynamic range, the CS4340A delivers superior sound quality. This D/A converter offers true ease of implementation, lower overall system costs, and shorter design cycles. Its features and competitive pricing make it perfect for mass-market consumer entertainment products.
