DESCRIPTION
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 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 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.
