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.
