National Semiconductor Semiconductors Linear |.C.s - Operational Amplifiers L.M102 Series Operational Amplifiers REFERENCE TABLE Code Stock No. LM102H 29363B LM202H 30542R LM302H 19662A GENERAL DESCRIPTION The LM102 series are high-gain operational amplifiers designed specifically for unity-gain voltage follower applications. Built on a single silicon chip, the device incorporates 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 stabilised component oven to get extremely low input currents and low offset voltage drift. TYPICAL APPLICATIONS* * FEATURES Fast slewing 10V/us Low input current 10nA (max) LM102 15nA (max) LM202 30nA (max) LM302 High input resistance 10000 MQ (LM102/LM202) 1000 MQ (LM302) No external frequency compensation required Simple offset balancing with optional 1KQ potentiometer - Plug-in replacement for both the LM101 and LM709 in voltage follower applications. The LM102 series, which are designed to operate with supply voltages between | 12V and - 15V, also feature low input capacitance as well as excellent small signal and large signal frequency response all of which minimise high frequency gain error. Because of the low wiring capacitances inherent in monolithic construction, this fast operation can be realised without increasing power consumption.
