A2212

AiT Semiconductor Inc. www.ait-ic.com A2212 AUDIO AMPLIFIER 1. 2 WATT AUDIO POWER AMPLIFIER DESCRIPTION FEATURES The A2212 is a Class-AB audio power amplifier designed for mobile phones and other portable communication devices. It is capable of delivering  Improved PSRR at 217 Hz 70dB  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: 430mW (typ.)  Ultra low shutdown current: 0.1uA (typ.) The A2212 was designed specifically to provide high quality output power with a minimal amount of  2.2V ~ 5.5V operation external components. 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...
