EMA2204
2.7W/Ch Stereo Fully Differential Audio Power
Amplifier with Bypass Capacitor Free
General Description
The EMA2204 is a 2.7W/Ch Stereo fully differential
amplifier designed to drive a speaker with at least 4Ω
impedance. The device operates from 2.2 V to 5.5 V,
drawing 9mA(Typ.) of quiescent supply current. The
EMA2204 performs superior THD+N and PSRR with no
bypass capacitor required.
With no bypass capacitor, the EMA2204 is ideal for PMPs
applications due to features such as -65dB supply
voltage rejection from 20 Hz to 10kHz, improved RF
rectification immunity and a fast startup with minimal
pop.
Features
．2.7 W/Ch Into 4Ω From a 5-V Supply at THD = 10% (Typ)
．Low Supply Current: 9mA (Typ) at 5 V
．Shutdown Current: 0.1 μA (Typ)
．Fast Startup With Minimal Pop
．Improved PSRR (-65 dB) and Wide Supply Voltage (2.2
V to 5.5 V) for Direct Battery Operation
．Fully Differential Design Reduces RF Rectification
．-63 dB CMRR Eliminates Two Input Coupling Capacitors
．Available in 3 mm X 3 mm TDFN Package
Applications
． PMPs
． Desktop
． Notebook
