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 ?lm resis-tors, and the output is stable over a wide range of tempera- ture and supply variations. The ICL8038 may be interfaced with phase locked loop circuitry to reduce temperature drift  to less than 250ppm/.
