TPA6211A1DRB

DESCRIPTION The TPA6211A1DRB is a 3.1-W mono fully-differential amplifier designed to drive a speaker with at least 3-Ω impedance while consuming only 20 mm(2) 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 TPA6211A1DRB is available in the space-saving 3-mm × 3-mm QFN (DRB) and the 8-pin MSOP (DGN) PowerPAD™ 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 TPA6211A1DRB ideal for PDA/smart phone applications.
