3 Description

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 spacesaving

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.
