3.1-W MONO FULLY DIFFERENTIAL AUDIO POWER AMPLIFIER

Check for Samples: TPA6211A1-Q1

FEATURES

APPLICATIONS

•

Qualified for Automotive Applications

Designed for Wireless or Cellular Handsets

and PDAs

•

Automotive Audio

Emergency Call

Driver Notifications

•

3.1 W Into 3Ω From a 5-V Supply at

THD = 10% (Typ)

DESCRIPTION

•

Low Supply Current: 4 mA Typ at 5 V

Shutdown Current: 0.01 μA Typ

Fast Startup With Minimal Pop

Only Three External Components

The TPA6211A1-Q1 is a 3.1-W mono fully-differential

amplifier designed to drive a speaker with at least

3-Ω impedance while consuming only 20 mm²total

printed-circuit board (PCB) area in most applications.

The device operates from 2.5 V to 5.5 V, drawing

–

Improved PSRR (-80 dB) and Wide Supply

Voltage (2.5 V to 5.5 V) for Direct Battery

Operation

only

4 mA of quiescent supply current. The

TPA6211A1-Q1 is available in the space-saving 8-pin

MSOP (DGN) PowerPAD™ package.

–

Fully Differential Design Reduces RF

Rectification

-63 dB CMRR Eliminates Two Input

Coupling Capacitors

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-Q1 ideal for emergency call

applications.

5 V DC
