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. 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.
