1.25-W MONO FULLY DIFFERENTIAL AUDIO POWER AMPLIFIER
FEATURES
· · · · 1.25 W Into 8 From a 5-V Supply at THD = 1% (Typ) Low Supply Current: 1.7 mA typ Shutdown Control <1 µA Only Five External Components Improved PSRR (90 dB) and Wide Supply Voltage (2.5 V to 5.5 V) for Direct Battery Operation Fully Differential Design Reduces RF Rectification Improved CMRR Eliminates Two Input Coupling Capacitors C(BYPASS) Is Optional Due to Fully Differential Design and High PSRR ZQV (Pb - free) and GQV Options Avaliable in a 2 mm x 2 mm MicroStar JuniorTM BGA Package ZQV (Pb - free) and GQV Options
APPLICATIONS
· Designed for Wireless or Cellular Handsets and PDAs
DESCRIPTION
The TPA6203A1 is a 1.25-W mono fully differential amplifier designed to drive a speaker with at least 8- impedance while consuming less than 37 mm2 total printed-circuit board (PCB) area in most applications. This device operates from 2.5 V to 5.5 V, drawing only 1.7 mA of quiescent supply current. The TPA6203A1 is available in the space-saving 2 mm x 2 mm MicroStar JuniorTM BGA package. Features like 85-dB PSRR from 90 Hz to 5 kHz, improved RF-rectification immunity, and small PCB area makes the TPA6203A1 ideal for wireless handsets. A fast start-up time of 4 µs with minimal pop makes the TPA6203A1 ideal for PDA applications.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
