| SPEMA2004A Elektronische Bauelemente 1.7W Mono Fully Differential Audio Power Amplifier RoHS Compliant Product A suffix of "-C" specifies halogen or lead -free DESCRIPTION The SPEMA2004A is a 1.7W mono fully differential amplifier designed to drive a speaker with at least 8 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 4mA of quiescent supply current. The SPEMA2004A is available in the space-saving 3 mm x 3 mm FBP package. The SPEMA2004A is ideal for PDA/smart phone applications due to features such as -70dB supply voltage rejection from 20 Hz to 2 kHz, improved RF rectification immunity, small PCB area, and a fast startup with minimal pop. FEATURES Designed for Wireless or Cellular Handsets and PDAs 1.7 W Into 8 From a 5-V Supply at THD = 10% (Typ) Low Supply Current: 5mA (Typ) at 5 V Shutdown Current: 0.1 A (Typ) Fast Startup With Minimal Pop Only Three External Components Improved PSRR (-70 dB) and Wide Supply Voltage (2.5 V to 5.5 V) for Direct Battery Operation Fully Differential Design Reduces RF Rectification -63 dB CMRR Eliminates Two Input Coupling Capacitors Pin to Pin Compatible with TPA2005D1 and TPA6211A1 in FBP Package Available in 3 mm X 3 mm TDFN Package PACKAGE DIMENSIONS TDFN-8 TOP VIEW REFERENCE A A3 b D D2 E E2 e L BOTTOM VIEW DIMENSIONS MILLIMETER MIN.
