Precision Waveform Generator/Voltage
Controlled Oscillator
The ICL8038 waveform generator is a monolithic integrated
circuit capable of producing high accuracy sine, square,
triangular, sawtooth and pulse waveforms with a minimum of
external components. The frequency (or repetition rate) can
be selected externally from 0.001Hz to more than 300kHz
using either resistors or capacitors, and frequency
modulation and sweeping can be accomplished with an
external voltage. The ICL8038 is fabricated with advanced
monolithic technology, using Schottky barrier diodes and thin
film resistors, and the output is stable over a wide range of
temperature and supply variations. These devices may be
interfaced with phase locked loop circuitry to reduce
temperature drift to less than 250ppm/
