CS4461-CZZR Datasheet PDF - Cirrus Logic

General Description
The CS4461 is a complete analog-to-digital converter for class-D real-time power supply rejection (PSR) feedback. It performs sampling and analog-to-digital conversion, generating digital data for input to a class-D modulator with real-time PSR feedback capabilities.

FEATUREs
● Advanced Multi-bit Delta-Sigma Architecture
