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.
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, 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.
The CS4361 is available in a 20-pin TSSOP Commer-
cial grade package (-40 to 85° C). The CDB4361 is also
available for device evaluation and implementation sug-
gestions. Please refer to “Ordering Information” on
page 23 for complete ordering information.
