www.DataSheet4U.com CS4461 Multi-Bit A/D for Class-D Real-Time PSR Feedback Features z Advanced Multi-bit Delta-Sigma Architecture z Real-time Feedback of Power Supply 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. 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 components and is ideal for class-D audio systems requiring high power supply rejection.
