Fairchild Debuts FAN7023 Power Amplifier IC
Fairchild Semiconductor International (San Jose, CA) announced its new FAN7023 CMOS power amplifier for mobile phones, PDAs and portable audio systems. The FAN7023 is a monaural power amplifier available in both a space-saving, mini SO-8 and an SO-8 package.
When delivering 1.0W of continuous RMS power into an 8 ohm speaker at 5V supply, the FAN7023 typically has 0.1 percent of total harmonic distortion plus noise. The FAN7023 operates from a 2.2V to 5.5V supply. The amplifier's THD and power supply rejection ratio (typically 65dB) characteristics guarantee high output performance. With low supply current characteristics and shutdown function, as well as low shutdown current consumption of 0.1µA typical, the FAN7023 is well suited for battery-powered portable applications requiring energy savings and a long battery life.
The FAN7023 features thermal shutdown protection, unity gain stability and external gain configuration capability. Board space is reduced because designs using the FAN7023 do not need an output coupling capacitor, bootstrap capacitor or a snubber network. Complementing the FAN7023 is a broad array of Fairchild's signal path solutions ranging from high-performance, low-power operational amplifiers to analog switches that provide optimum performance with a minimum power budget.
Pricing for the FAN7023 is $0.57 in 1,000-piece quantities. Available now, delivery is 8 to 10 weeks ARO.
