and PDAs DESCRIPTION
The TPA6203A1 is a 1.25-W mono fully differential
amplifier designed to drive a speaker with at least
8-Ω impedance while consuming less than 37 mm2
(ZQV package option) total printed-circuit board
(PCB) area in most applications. This device operates
from 2.5 V to 5.5 V, drawing only 1.7 mA of quiescent
supply current. The TPA6203A1 is available in the
space-saving 2 mm x 2 mm MicroStar Juniorв„ў BGA …
