3 Description
The TPA6211A1 is a 3.1-W mono fully-differential
amplifier designed to drive a speaker with at least 3-
Ω 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 SON (DRB) and the 8-pin MSOP-
PowerPAD™ (DGN) 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 and smart
phone applications.
