EMA2204

ESMT/EMP 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.
