The BA3472F-E2 from Rohm is a high-performance two-channel audio amplifier made for industrial audio applications. It features dual output volume and mute control with L-ehanced (E2) devices for improved sonic performance and low noise. This audio amplifier is ideal for low-power active speakers, amplifier consoles, and portable audio equipment.

The BA3472F-E2 is a dual-channel audio amplifier that integrates two 2-channel audio amplifying stages, one for the left channel and one for the right channel, in a single device. Each channel consists of a low-noise voltage-gain stage, a differential input stage, and outputs of up to 16 watts. The differential input stage provides excellent audio quality with balanced input signals and a wide bandwidth. The amplifier has separate mute control pins for each channel, allowing for precise and silent muting of each channel\'s audio.

The BA3472F-E2 offers excellent sound quality, low noise, and low distortion. The device uses L-enhanced soft-switch technology to minimize crossover noise and distortion. This allows for improved linearity in the audio and higher power output. The device features low quiescent current for improved noise performance and low power consumption.

The BA3472F-E2 has a wide range of applications in audio equipment such as active speakers, amplifiers, PA systems, automotive audio systems, and home audio systems. It is suitable for applications where high quality sound, low noise, and low distortion are required.
