The LM102 series are high-gain operational amplifiers designed specifically for unity-gain voltage follower applications 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 transistors are operated at zero collector-base voltage to virtually eliminate high temperature leakage currents It can therefore be operated in a temperature stabilized component oven to get extremely low input currents and low offset voltage drift The LM102 which is designed to operate with supply voltages between g 12V and g 15V also features low input capacitance as well as excellent small signal and large signal frequency response all of which minimize high fre-
