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.
