Description
The TPA6204A1 (sometimes referred to as TPA6204) is a 1.7-W mono fully-differential amplifier designed to drive a speaker with at least 8-Ωimpedance while consuming only 20 mm(2) 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 device is available in the space-saving 3 mm x 3 mm QFN (DRB) package.
The TPA6204 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.
