ICL8038; ge Controlled Oscillator The ICL8038 wav eform generator is a monolithic integra ted circuit capable of producing high a ccuracy sine, square, triangular, sawto oth and pulse waveforms with a minimum of external components. The frequency ( or repetition rate) can be selected ext ernally from 0.001Hz to more than 300kH z using either resistors or capacitors, and frequency mod.

ulation and sweeping can be accomplished with an external voltage. The ICL8038 is fabricated with advanced monolithic technology, using Schottky barrier diod es and thin film resistors, and the out put is stable over a wide range of temp erature and supply variations. These de vices may be interfaced with phase lock ed loop circuitry to reduce temperature drift to less tha.

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/oC.
