Texas Instruments TPA6203A1EVM
The TPA6203A1 is a 1.25-W mono fully differentialamplifier designed to drive a speaker with at least 8-Ohm impedance while consuming less than 37 mm2 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.
