A2203
AUDIO AMPLIFIER
1.1 WATT AUDIO POWER AMPLIFIER
DESCRIPTION
FEATURES
The A2203 is a Class-AB audio power amplifier
designed for mobile phone, MID and other portable
communication devices. It is capable of delivering 1.1
watts of continuous average power to an 8Ω BTL load
with less than 1% distortion (THD+N) from a 5VDC
power supply.
The A2203 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 A2203 is ideally suited for
mobile phone, MID and other low voltage applications
where minimal power consumption is a primary
requirement.
With special pop-click eliminating circuit, the A2203
provides perfect pop-click characteristic during turn-on
and turn-off transitions.
The A2203 is unity-gain stable and can be configured
by external gain-setting resistors.
Improved PSRR at 217 Hz & 1 KHz: 60dB
Power output at 5.0V, 1% THD+N, 8Ω:
1.1W (typ.)
Ultra low shutdown current: 0.1uA (typ.)
2.2V ~ 5.5V operation
Improved circuitry eliminates pop-click noise
during turn-on and turn-off transitions
No output coupling capacitors, snubber
networks or bootstrap capacitors required
Unity-gain stable
External gain configuration capability
Available in MSOP8 and SOP8 Packages
