Description
The ICL8038 waveform generator is a monolithic integrated
circuit capable of producing high accuracy sine, square, tri-
angular, 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 modula-
tion and sweeping can be accomplished with an external
voltage. The ICL8038 is fabricated with advanced monolithic
technology, using Schottky barrier diodes and thin film resis-
tors, and the output is stable over a wide range of tempera-
ture and supply variations. These devices may be interfaced
with phase locked loop circuitry to reduce temperature drift
to less than 250ppm/oC.
