TPA6204A1 - 1.7-W Mono, Fully Differential, Class-AB Audio Amplifier

The TPA6204A1 device (sometimes referred to as TPA6204) is a 1.7-W mono fully-differential amplifier designed to drive a speaker with at least 8-Ω 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 (TPA6204) is available in the space-saving 3 mm × 3 mm SON (DRB) package.

The TPA6204A1 (TPA6204) is ideal for PDA or smartphone 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 start-up with minimal pop.
