DESCRIPTIO
The LT®1010 is a fast, unity-gain buffer that can increase
the output capability of existing IC op amps by more than
an order of magnitude. This easy-to-use part makes fast
amplifiers less sensitive to capacitive loading and reduces
thermal feedback in precision DC amplifiers.
Designed to be incorporated within the feedback loop, the
buffer can isolate almost any reactive load. Speed can be
improved with a single external resistor. Internal operat-
ing currents are essentially unaffected by the supply
voltage range. Single supply operation is also practical.
This monolithic IC is supplied in 8-pin miniDIP, plastic
TO-220 and 8-pin DFN packages. The low thermal resis-
tance power package is an aid in reducing operating
junction temperatures.
