AUDIO AMPLIFIER

1.3W AUDIO POWER AMPLIFIER

DESCRIPTION

FEATURES

The A2212 is a Class-AB audio power amplifier

designed for mobile phones and other portable

communication devices. It is capable of delivering

1.3 watts of continuous average power to an 8Ω

BTL load with less than 1% distortion (THD+N)

from a 5V_DCpower supply.



Improved PSRR at 217 Hz 68dB

Power output at 5.0V, 1% THD+N, 8Ω: 1.3W (typ.)

Power output at 3.0V, 1% THD+N, 8Ω: 480mW

(typ.)



Ultra low shutdown current: 0.1uA (typ.)

2.2V ~ 5.5V operation

The A2212 was designed specifically to provide

high quality output power with a minimal amount of

external components. It does not require output

coupling capacitors or bootstrap capacitors. And

with ultra low shutdown current, the A2212 is

ideally suited for mobile phone and other low

voltage applications where minimal power

consumption is a primary requirement.

Improved circuitry eliminates pop-click noise

during turn-on and turn-off transitions

Excellent RFI (Radio Frequency Interference)

immunity



No output coupling capacitors, snubber

networks or bootstrap capacitors required

Unity-gain stable



External gain configuration capability

Available in CSP9 package

With special pop-click eliminating circuit, the A2212

provides perfect pop-click characteristic during

turn-on and turn-off transitions.

APPLICATION

The A2212 is unity-gain stable and can be

configured by external gain-setting resistors.



Wireless handsets

Portable electronic devices

PDAs, Handheld computers

The A2212 is available in CSP9 package
