LT1010 Fast 150mA Power Buffer FTEATURES DESCRIPTION n 20MHz Bandwidth The LT 1010 is a fast, unity-gain buffer that can increase n 75V/s Slew Rate the output capability of existing IC op amps by more than n Drives 10V Into 75 an order of magnitude. This easy-to-use part makes fast n 5mA Quiescent Current amplifiers less sensitive to capacitive loading and reduces n Drives Capacitive Loads > 1F thermal feedback in precision DC amplifiers. n Current and Thermal Limit Designed to be incorporated within the feedback loop, the n Operates from Single Supply 4.5V buffer can isolate almost any reactive load. Speed can be n Very Low Distortion Operation improved with a single external resistor. Internal operating n Available in 8-Pin miniDIP, Plastic TO-220 currents are essentially unaffected by the supply voltage and Tiny 3mm 3mm 0.75mm 8-Pin DFN Packages range. Single supply operation is also practical. This monolithic IC is supplied in 8-pin miniDIP, plastic APPLICATIONS TO-220 and 8-pin DFN packages. The low thermal re- sistance power package is an aid in reducing operating n Boost Op Amp Output junction temperatures. n Isolate Capacitive Loads n Drive Long Cables L, LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
