Description
The CS4361 is a complete 6-channel digital-to-analog
output system including interpolation, multi-bit D/A
conversion, and output analog filtering in a small 20-pin
package. The CS4361 supports all major audio data
interface formats.
The CS4361 is based on a fourth order, multi-bit, delta-
sigma modulator with a linear analog low-pass filter. This
device also includes auto-speed mode detection using
both sample rate and master clock ratio as a method of
auto-selecting sampling rates between 2 kHz and
216 kHz.
The CS4361 contains on-chip digital de-emphasis, oper-
ates from a single +3.3 V or +5 V power supply with
separate built-in level shifter for the digital interface, and
requires minimal support circuitry. These features are
ideal for DVD players & recorders, digital televisions,
home theater and set top box products, and automotive
audio systems.
