The TPA6211A1 is a 3.1-W mono fully-differential amplifier designed to drive a speaker with at least 3-W impedance while consuming only 20 mm2 total printed-circuit board (PCB) area in most applications.
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.
* Based on board 296-18929-ND The TPA6211A1 is a 3.1-W mono fully-differential amplifier designed to drive a speaker with at least 3-W impedance while consuming only 20 mm2 total printed-circuit board (PCB) area in most applications.
