EMA2004 Datasheet | Elite Semiconductor Microelectronics Technology

ESMT/EMP General Description 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 5m A of quiescent supply current. The EMA2004 is available in the space-saving 3 mm x 3 mm TDFN package. The EMA2004 is ideal for PDA/smart phone applications due to Features such as -70d B supply voltage rejection from 20 Hz to 2 k Hz, improved RF rectification immunity, small PCB area, and a fast startup with minimal pop. 2.7W Mono Fully Differential Audio Power Amplifier Features ．Designed for Wireless or Cellular Handsets and PDAs ．2.7 W Into 4Ω From a 5-V Supply at THD = 10% (Typ) ．Low Supply Current: 5m A (Typ) at 5 V ．Shutdown Current: 0.1 μA (Typ) ．Fast Startup With Minimal Pop ．Only Three External ponents ．Improved PSRR (-70 d B) and Wide Supply Voltage (2.5 V to 5.5 V) for Direct Battery Operation ．Fully Differential Design Reduces RF Rectification ．-63 d B CMRR Eliminates Two Input Coupling Capacitors ．Pin to Pin patible With TPA6204A1 in TDFN Package ．Available in 3 mm X 3 mm TDFN Package Applications ． Ideal for Wireless Handsets ． PDAs ． Notebook puters Elite Semiconductor Memory Technology Inc./Elite Micro Power Inc.
