CS43L41
Low Power 24-Bit, 96 kHz DAC with Volume Control
Features
l
Complete Stereo DAC System: Interpolation,
Description
The CS43L41 is a complete stereo digital-to-analog sys-
tem 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 tempera-
ture 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 oper-
ates over a wide power supply range. These features are
ideal for portable DVD, portable MP3, Mini-Disc, and
mobile phones.
