Description
The CS4461 is an analog-to-digital converter designed for real-time power supply rejection (PSR) feedback in class-D audio systems. It uses a multi-bit delta-sigma architecture to perform sampling and analog-to-digital conversion, generating digital data for input to a class-D modulator. The CS4461 features a differential analog architecture, which provides excellent noise rejection. It also has a filterless digital output, resulting in very low signal delay.
Features
Advanced multi-bit delta-sigma architecture
Real-time feedback of power supply conditions (AC and DC)
Filterless digital output resulting in very low signal delay
135 mW power consumption
Supports logic levels between 3.3 V and 5.0 V
Differential analog architecture
Modulator overflow detection
Interfaces directly to the CS44800/CS44600 class-D PWM modulator
Multi-bit conversion at up to 7.5 MHz
Delivers modulated data over 2-wire interface
Applications
Class-D audio systems requiring high power supply rejection
