FEATURES D Designed for Wireless or Cellular Handsets D
and PDAs 1.7 W Into 8 From a 5-V Supply at THD = 10% (Typ) Low Supply Current: 4 mA typ at 5 V Shutdown Current: 0.01 mA Typ
APPLICATIONS D Ideal for Wireless Handsets D PDAs D Notebook Computers DESCRIPTION
The TPA6204A1 is a 1.7-W mono fully-differential amplifier designed to drive a speaker with at least 8- impedance while consuming only 20 mm2 total printed-circuit board (PCB) area in most applications. The device operates from 2.5 V to 5.5 V, drawing only 4 mA of quiescent supply current. The TPA6204A1 is available in the space-saving 3 mm x 3 mm QFN (DRB) package. The TPA6204A1 is ideal for PDA/smart phone applications due to features such as -80-dB supply voltage rejection from 20 Hz to 2 kHz, improved RF rectification immunity, small PCB area, and a fast startup with minimal pop.

(1) 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.
