Elite Semiconductor EMA2004

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.
