TPA6211A1 Description
The TPA6211A1 is a 3.1-W mono fully-differential amplifier designed to drive a speaker with at least 3Ω impedance while consuming only 20 mm2 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 TPA6211A1 is available in the space-saving 3-mm × 3-mm SON (DRB) and the 8-pin MSOPPowerPAD™ (DGN) packages.
