LM102/LM302 Voltage Followers
General Description
The LM102 series are high-gain operational amplifiers de-
signed specifically for unity-gain voltage follower applica-
tions. Built on a single silicon chip, the devices incorporate
advanced processing techniques to obtain very low input
current and high input impedance. Further, the input transis-
tors are operated at zero collector-base voltage to virtually
eliminate high temperature leakage currents. It can there-
fore be operated in a temperature stabilized component
oven to get extremely low input currents and low offset volt-
age drift.
The LM102, which is designed to operate with supply volt-
ages between
g
12V and
g
15V, also features low input
capacitance as well as excellent small signal and large sig-
nal frequency responseDall of which minimize high fre-
quency gain error. Because of the low wiring capacitances
inherent in monolithic construction, this fast operation can
be realized without increasing power consumption.
