LM4671 Filterless High Efficiency 2.5W Switching Audio Amplifier

The LM4671 is a single supply, high efficiency 2.5W switching 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 LM4671 is designed to meet the demands of mobile p.

LM4671 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 LM4671 is externally configurable which allows independent gain control from multiple sources by summing the signals. Key Specifications

* Efficiency @ 3.6V, 100mW in
