AiT Semiconductor A2203
The A2203 is a Class-AB audio power amplifier primarily designed for demanding mobile phones 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 does not require output coupling capacitors or bootstrap capacitors.| Part No. | A2203 |

DESCRIPTION
FEATURES
Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. The A2203 is ideally suited for mobile phone, and other low voltage applications where minimal power consumption is a primary requirement. The A2203 features a low-power consumption shutdown mode. To facilitate this, Shutdown may be enable by either logic high or low pending on mode selection. Driving the shutdown mode pin either high or low enable the shutdown pin to be driven in a likewise manner to enable shutdown. The A2203 contains advanced pop-click circuitry which eliminates noise, which would otherwise occur during turn-on and turn-off transitions. The A2203 is unity-gain stable and can be configured by external gain-setting resistors. The A2203 is available in MSOP8 and SOP8 packages● Ultra low shutdown current: 0.1uA (typ.)
● Improved PSRR at 217 Hz & 1 kHz: 60dB
● 2.2V ~ 5.5V operation
● Power output at 5.0V, 10%THD...
