EMA2004 - 2.7W Mono Fully Differential Audio Power Amplifier

General 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.

Key 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. EMA2004 2.7W Mono Fully Differential Audio Power Amplifier Features ．Designed for Wireless or Cellular Handsets and PDAs ．2.7 W Into 4Ω From a 5-V Supply at THD = 10% (Typ) ．Low Supply Current: 5mA (Typ) at 5 V ．Shutdown Current: 0.1 μA (Typ) ．Fast Startup With Minimal Pop ．Only Three External Components ．Improved PSRR (-70 dB) and Wide Supply Vol.

ESMT/EMP General 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. The EMA2004 is available in the space-saving 3 mm x 3 mm TDFN package. The EMA2004 is ideal for PDA/smart phone applications due to 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.
