A2212 Datasheet | AiT Semiconductor

DESCRIPTION FEATURES The A2212 is a Class-AB audio power amplifier designed for mobile phones and other portable munication devices. It is capable of delivering - Improved PSRR at 217 Hz 70d B - Power output at 5.0V, 1% THD+N, 8Ω: 1.2W (typ.) 1.2 watts of continuous average power to an 8ΩBTL load with less than 1% distortion (THD+N) from a 5VDC power supply. - Power output at 3.0V, 1% THD+N, 8Ω: 430m W (typ.) - Ultra low shutdown current: 0.1u A (typ.) The A2212 was designed specifically to provide high quality output power with a minimal amount of - 2.2V ~ 5.5V operation external ponents. It does not require output - Improved circuitry eliminates pop-click noise coupling capacitors or bootstrap capacitors. And with ultra low shutdown current, the A2212 is during turn-on and turn-off transitions ideally suited for mobile phone and other low - Excellent RFI (Radio Frequency Interference) voltage applications where minimal power consumption is a primary requirement. immunity With special pop-click eliminating circuit, the A2212 provides perfect pop-click characteristic during turn-on and turn-off transitions. - No output coupling capacitors, snubber networks or bootstrap capacitors required - Unity-gain stable The A2212 is unity-gain stable and can be configured by external gain-setting resistors. - External gain configuration capability - Available in CSP9 package The A2212 is available in CSP9 package APPLICATION ORDERING INFORMATION - Wireless handsets - Portable electronic devices - PDAs, Handheld puters Package Type Part Number CSP9 A2212G9R G9 A2212G9VR Note R: Tape & Reel V: Halogen free Package Ai T provides all Ro HS products Suffix “V” means Halogen free Package TYPICAL APPLICATION REV1.0 - FEB 2012 RELEASED - -1- Ai T Semiconductor Inc. .ait-ic.
