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 BL6281G was designed specifically to provide high quality output power with a minimal amount of external ponents. It does not require output coupling capacitors or bootstrap capacitors. And with ultra low shutdown current, the BL6281G 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 BL6281G provides perfect pop-click characteristic during turn-on and turn-off transitions. The BL6281G is unity-gain stable and can be configured by external gain-setting resistors.
