EMA2204 Datasheet | Elite Semiconductor Microelectronics Technology

ESMT/EMP 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 9m A(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 -65d B supply voltage rejection from 20 Hz to 10k Hz, improved RF rectification immunity and a fast startup with minimal pop.
