ICL8038
1 SemiconductorCAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Harris Corporation 1998 ICL8038 Precision Waveform Generator/VoltageControlled OscillatorThe ICL8038 waveform generator is a monolithic integratedcircuit capable of producing high accuracy sine, square,triangular, sawtooth and pulse waveforms with a minimum ofexternal components. The frequency (or repetition rate) canbe selected externally from to more than 300kHzusing either resistors or capacitors, and frequencymodulation and sweeping can be accomplished with anexternal voltage. The ICL8038 is fabricated with advancedmonolithic technology, using Schottky barrier diodes and thinfilm resistors, and the output is stable over a wide range oftemperature and supply variations. These devices may beinterfaced with phase locked loop circuitry to reducetemperature drift to less than 250 Low Frequency Drift with Temperature.
5 The levels of the current sources can, however, be selected over a wide range with two external resistors. Therefore, with the two currents set at values different from I and 2I, an
