–63 dB CMRR Eliminates Two Input Coupling Capacitors
The TPA6211A1 is a 3.1-W mono fully-differential amplifier designed to drive a speaker
with at least 3-Ω 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 MSOP-PowerPAD (DGN) packages.
Features like –80 dB supply voltage rejection from
20 Hz to 2 kHz, improved RF rectification immunity, small PCB area, and a fast startup with
minimal pop makes the TPA6211A1 ideal for PDA and smart phone applications.
