EMA2004 - 2.7W Mono Fully Differential Audio Power Amplifier

Datasheet Summary

Description

The EMA2004 is a 2.7W mono fully differential amplifier designed to drive a speaker with at least 4Ω impedance while consuming only 20 mm2 total PCB area in most applications.

The device operates from 2.5 V to 5.5 V, drawing only 5mA of quiescent supply current.

Features

  • such as -70dB supply voltage rejection from 20 Hz to 2 kHz, improved RF rectification immunity, small PCB area, and a fast startup with minimal pop.
