General Description
The LM110 seriesare monolithic operational amplifiersin-
ternally connectedas unity-gain non-inverting amplifiers.
Theyuse super-gain transistorsinthe input stagetogetlow
bias current without sacrificing speed. Directly interchange-
able with 101,741and709in voltage follower applications,
these devices have internal frequency compensation and
provisionfor offset balancing.
The LM110 seriesare usefulinfast sampleand holdcir-
cuits, active filters,oras general-purpose buffers. Further,
the frequency responseis sufficiently better than standard amplifiersthatthe followerscanbe includedinthe feed-
back loop without introducing instability. Theyare plug-in
replacementsforthe LM102 series voltage followers, offer-
ing lower offset voltage, drift, bias currentand noisein addi-
tionto higher speedand wider operating voltage range.
The LM110is specified overa temperature range b55§Css a125§C,the LM210 from b25§CsTAs a85§Cand
the LM310 from0§CsTAs a70§C.
Features Input current 10nA max over temperature Small signal bandwidth 20 MHz Slew rate 30 V/ms Supply voltage range g5Vto g18V
