A2210 Datasheet | AiT Semiconductor

DESCRIPTION The A2210 is a Class-AB audio power amplifier designed for mobile phones and other portable munication devices. It is capable of delivering 1.2W of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5V DC power supply. The A2210 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 A2210 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 A2210 provides perfect pop-click characteristic during turn-on and turn-off transitions. The A2210 is unity-gain stable and can be configured by external gain-setting resistors. The A2210 is available in MSOP8 package.
