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 Junior
BGA package, and the space saving 3 mm x 3 mm QFN (DRB) package.Features like 85-dB PSRR from 90 Hz to 5 kHz, improved RF-rectification
immunity, and small PCB area makes the TPA6203A1 ideal for wireless handsets. A
fast start-up time of 4 µs with minimal pop makes the TPA6203A1 ideal for PDA
applications.
