FEATURES
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.

Operates from Single Supply ≥ 4.5V

Available in 8-Pin miniDIP, Plastic TO-220
and Tiny 3mm × 3mm × 0.75mm 8-Pin DFN
Packages
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.
