AN ultra-miniature CMOS power amplifier from Fairchild Semiconductor, represented by Arrow Electronics , offers designers of mobile phones, PDAs and portable audio applications 1.0W of continuous power - allied to extremely low shutdown power and a minimal external part count.
Fairchild is offering the FAN7023 monaural power amplifier in a space-saving, mini SO-8 package with a footprint of just 3mm x 4.8mm, as well as a standard SO-8 package.
When delivering 1.0W of continuous rms power into an 8Ω 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 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 analogue switches that provide optimum performance with a minimum power budget.
