General Description
The CS4461 is a complete analog-to-digital converter
for class-D real-time power supply rejection (PSR) feed-
back. It performs sampling and analog-to-digital
conversion, generating digital data for input to a
class-D modulator with real-time PSR feedback
capabilities.
The CS4461 uses a 5th-order, multi-bit delta-sigma
modulator followed by output data formatting. The ADC
uses a differential architecture which provides excellent
noise rejection.
The CS4461 feeds back the AC and DC voltage compo-
nents and is ideal for class-D audio systems requiring
high power supply rejection.
The CS4461 is available in a 24-pin TSSOP package in
both Commercial (-10° to +70° C) and Automotive
grade (-40° to +85° C). The CDB44800 Customer Dem-
onstration board is also available for device evaluation
and implementation suggestions. Please see “Ordering
Information” on page 11 for complete details.
