Fairchild Semiconductors LM 101A, 201A, 301A, General Purpose Operational Amplifiers GENERAL DESCRIPTION The 101A and 301A are General Purpose monolithic Operational Amplifiers constructed using the Fairchild Planar epitaxial process. These integrated circuits are intended for applications requiring low input offset voltage or low input offset current. The accuracy of long interval integrators, timers and sample and hold circuits is improved due to the low drift and low bias currents of the 101A and 301A. Frequency response may be matched to the individual circuit need with one external capacitor. The absence of latch-up coupled with internal short circuit protection make the 101A, 201A and 301A virtually foolproof. The 101A, 301A are pin compatible with the popular A709, A741, .A748 and A777. FEATURES Low offset current and voltage, Low offset current drift. Low bias current. Short circuit protected. Low power consumption.

Advanced processing techniques make possible an order of magnitude reduction in input currents, and a redesign of the biasing circuitry reduces the temperature drift of input current. . This amplifier offers many features which make its application nearly foolproof: overload protection on the input and output, no latch-up when the common mode range is exceeded, freedom from oscillations and compensation with a single 30pF capacitor. It has advantages over internally compensated amplifiers in that the compensation can be tailored to the particular application. For example, as a summing amplifier, slew rates of 10 V/us and bandwidths of 10 MHz can be to make it compatible with logic circuits. The LM301A provides better accuracy and lower noise than its predecessors in high impedance circuitry. The low input currents also make it particularly well suited for long interval integrators or timers, sample and hold circuits and low frequency waveform generators. Further, replacing circuits where matched transistor pairs buffer the inputs of conventional IC op amps, it can give lower offset voltage and drift at reduced cost. .
