3 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 m A of quiescent supply current. The TPA6211A1 is available in the space-saving 3-mm × 3-mm SON (DRB) and the 8-pin MSOPPower PAD™ (DGN) packages.
Features like
- 80 d B supply voltage rejection from 20 Hz to 2 k Hz, improved RF rectification immunity, small PCB area, and a fast startup with minimal pop makes the TPA6211A1 ideal for PDA and smart phone applications.
