Low Voltage, 24-Bit, 96 kHz, D/A Converter with Volume Control

The CS43L41 is a complete, stereo, digital-to-analog system including digital interpolation, fourth-order Delta-Sigma digital-to-analog conversion, digital de-emphasis, volume control, channel mixing, and 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 CS43L41 accepts data at audio sample rates from 2 kHz to 100 kHz, consumes very little power, and operates over a wide power supply range. These features are ideal for portable DVD, portable MP3, mini-disc, and mobile phones.
