Precision Waveform Generator/Voltage
Controlled Oscillator
The ICL8038 waveform generator is a monolithic integrated
tle _{circuit capable of producing high accuracy sine, square,}
80 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
ci-
modulation and sweeping can be accomplished with an
external voltage. The ICL8038 is fabricated with advanced
monolithic technology, using Schottky barrier diodes and thin
e- film resistors, and the output is stable over a wide range of
temperature and supply variations. These devices may be
er- ^{interfaced with phase locked loop circuitry to reduce}
/Vo ^{temperature drift to less than 250ppm/oC.}
