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 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.
