         The CXAB4108 is a bridge-connected audio power amplifier capable of delivering typically 1.1W of continuous average power to an 82KPload with 0.5% (THD) from a 5V power supply. Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. Since the CXAB4108 does not require output    coupling capacitors, bootstrap capacitors, or snubber networks, it is optionally suited for low-power portable systems 。

        The CXAB4108 features an externally controlled, low-power  consumption shutdown mode, as well as an internal thermal shutdown protection mechanism。

        The unity-gain stable CXAB4108 can be configured by external   gain-setting resistors.
