The A2203A is an audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications. It is capable of delivering 1 watt of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5V DC power supply.

This Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal number of external components.

The A2203A does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for mobile phone and other low voltage applications where minimal power consumption is a primary requirement. 

This device also features a low-power consumption shutdown mode and an internal thermal shutdown protection mechanism. This device contains advanced pop & click circuitry which eliminates noises which would otherwise occur during turn-on and turn-off transitions.

The A2203A is available in MSOP8 and SOP8 packages.
