General Description
The BL6213 is a Class-AB audio power amplifier designed for mobile phones and other portable
communication devices. It is capable of delivering 1.2 watts of continuous average power to an
8Ω BTL load with less than 1% distortion (THD+N) from a 5VDC power supply.
The BL6213 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 BL6213 is ideally suited for mobile phone
and other low voltage applications where minimal power consumption is a primary requirement.
With special pop-click eliminating circuit, the BL6213 provides perfect pop-click characteristic
during turn-on and turn-off transitions.
The BL6213 is unity-gain stable and can be configured by external gain-setting resistors.
