CLASS AB 1.25 W DIFFERENTIAL AUDIO POWER AMPLIFIER

WITH INTERNAL FEEDBACK CIRCUIT

DESCRIPTION

FEATURES

The A2211 is a fully differential audio power amplifier



Fully Differential Amplifier

designed

for

portable

communication

device



Improved PSRR at 217Hz(V_DD>3.0V):

86dB(Typ.)

applications.



Power Output at 5.0V & 1% THD:

1.25W(Typ.)

The A2211 is capable of delivering 1.25W of

continuous average power to an 8Ω BTL load with less

than 1% distortion (THD+N) from a 5V battery voltage.

And operates from 2.2V to 5.5V.



Power Output at 3.6V & 1% THD: 0.6W(Typ.)

Ultra Low Shutdown Current: 0.01uA(Typ.)

Improved Pop & Click Circuitry Eliminates

Noise During Turn-on and Turn-off

Transitions

A2211 features 86dB PSRR at 217Hz, improved

RF-rectification immunity, the advanced pop & click

circuitry, a minimal count of external components and

low-power shutdown mode make A2211 idea for

wireless handsets.



Thermal Overload Protection Circuitry

No Output Coupling Capacitors, Bootstrap

Capacitors Required



Unity-Gain Stable

The A2211 is unity-gain stable, and the gain can be

configured by external input resistors and internal

feedback resistors.
