LM4673 Product details

Description

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.

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 prevent the device from damage during fault conditions. Key Specifications j Efficiency at 3.6V, 400mW into 8Ω speaker 88% (typ) j Efficiency at 3.6V, 100mW into 8Ω speaker 80% (typ) j Efficiency at.
