Features
Description
The CS4361 is a complete 6-channel digital-to-analog
output system including interpolation, multi-bit D/A con-
version, and output analog filtering in a small 20-pin
package. The CS4361 supports all major audio data in-
terface formats.
Multi-Bit Delta-Sigma Modulator
24-Bit Conversion
Automatically Detects Sample Rates Up To
192 kHz
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.
103 dB Dynamic Range
-94 dB THD+N
Low Clock-Jitter Sensitivity
+5 V Core Power
The CS4361 contains on-chip digital de-emphasis, op-
erates from a single +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 and recorders, digital televisions, home
theater and set-top box products, and automotive audio
systems.
