TPA6203A1 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 Junior™ BGA package, and the...
