LM4871MX General Description

Boomer audio power amplifiers like the LM4871MX are designed for maximum efficiency and minimal external component requirements. Operating on low supply voltages from 2.0V to 5.5V, this amplifier eliminates the need for output coupling capacitors, bootstrap capacitors, and snubber networks, reducing overall system complexity

Key Features

Low Quiescent Current Design
Wide Supply Voltage Range
Fault Tolerant Operation
