It measures just over 2 mm2, making it viable for cell phones, portable media players, netbooks, and other battery-powered audio applications. The MAX97200 operates from a single 1.8V supply and delivers 34 mW of output power into 32?. Prices start at $0.45 each/1,000. MAXIM INTEGRATED PRODUCTS, Sunnyvale, CA. (800) 998-8800.
