Power Amplifier IC suits portable audio applications.

Press Release Summary:

Model FAN7023 monaural, CMOS power amplifier comes in mini SO-8 and SO-8 package. When delivering 1.0 W of continuous RMS power into 8 ohm speaker at 5 V supply, unit typically has 0.1% of THD+N. It operates from 2.2-5.5 V supply, and Power Supply Rejection Ratio is typically 65 dB. With low supply current and shutdown function, as well as low shutdown current consumption of 0.1 microamp, FAN7023 is suited for battery-powered portable applications.

Original Press Release:

New 1W CMOS Power Amplifier IC in Space Saving Mini SO-8 Package Provides Excellent Sound Quality in Portable Audio Applications

San Jose, Calif.-December 13, 2002-Fairchild Semiconductor International (NYSE: FCS) announces the FAN7023, a CMOS power amplifier for mobile phone, PDA 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 % of THD+N (Total Harmonic Distortion plus Noise). The FAN7023 operates from 2.2V to 5.5V supply. The amplifier's superior THD and PSRR (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 (0.1 microamp, 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.
