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 g12V and g15V also features low input
capacitance as well as excellent small signal and large sig-
nal frequency response all 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
