TPA6211A1 - 3.1-W Mono Fully Differential Audio Power Amplifier

General 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 mA of quiescent supply current.

Key Features

  • 1 Designed for Wireless or Cellular Handsets and PDAs.
  • 3.1 W Into 3 Ω From a 5-V Supply at THD = 10% (Typ).
  • Low Supply Current: 4 mA Typ at 5 V.
  • Shutdown Current: 0.01 μA Typ.
  • Fast Startup With Minimal Pop.
  • Only Three External Components.
  • 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 Elimin.
