Fairchild Unveils New FAN7021 Power Amplifier
Fairchild Semiconductor International (San Jose, CA) announced the FAN7021, a CMOS power amplifier targeted for mobile phone, DECT phone, PDA and other portable applications. The FAN7021 produces up to 1W of low-distortion continuous output power (1.5W peak) with supply voltages from 2.0V to 5.5V.
The device utilizes an integrated adaptive bias current control circuit to minimize crossover distortion while consuming 54 percent lower quiescent supply current. Additionally, the FAN7021's exceptionally low bias-supply current, combined with low-shutdown current consumption (0.1µA), saves energy and extends battery life.
The FAN7021 power amplifier also features a built-in popping noise-reduction circuit to reduce unexpected speaker noise when the system's power is turned on or off. The FAN7021 reduces overall system footprint by not requiring an output coupling capacitor, a bootstrap capacitor or a snubber network. Other features include thermal shutdown protection, unity gain stability and external gain configuration capability.
Now available, the FAN7021 is offered in an 8-SOP package and comes in tube or tape-and-reel packing. The FAN7021 is priced at $0.55 for 1,000-piece quantities. Delivery is 8 to 10 weeks ARO.
