The TPA6211A1 is a 3.1-W mono fully-differential amplifier designed to drive a speaker with at least 3-O 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 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 TPA6211A1 ideal for PDA/smart phone applications.
- Improved PSRR (-80 dB) and Wide Supply Voltage
(2.5 V to 5.5 V) for Direct Battery Operation - Fully Differential Design Reduces RF Rectification
- –63 dB CMRR Eliminates Two Input Coupling Capacitors
- Ideal for Wireless Handsets, PDAs, and Notebook Computers
