LM4673 Datasheet (National Semiconductor) - Class D Audio Power Amplifier

LM4673, Class D Audio Power Amplifier

The LM4673 is a single supply, high efficiency, 2.65W, mono, Class D audio amplifier.

A low noise, filterless PWM architecture eliminates the output filter, reducing external component count, board area consumption, system cost, and simplifying design.

The LM4673 is designed to meet the demands of m

LM4673 Features

* a low-power consumption shutdown mode. Shutdown may be enabled by driving the Shutdown pin to a logic low (GND). The gain of the LM4673 is externally configurable which allows independent gain control from multiple sources by summing the signals. Output short circuit and thermal overload protection
