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

● 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
