The TPA6211A1 is a 3.1-W mono fully differential amplifier designed to drive a speaker with at least 3-Ohm impedance while comsuming less than 20mm2 total board space.
The device operates from 2.5V to 5.5V while consuming only 4mA of quiescent current. The TPA6211A1 is available in a space-saving 3mm x 3mm QFN (Quad Flat No Lead) package and the 3mm x 5mm MSOP package.
Features like 70-dB improved RF rectification immunity, and small PCB area makes the TPA6211A1 ideal for wireless handsets. The fast start-up time of less than 1ms is great for PDA applications.
