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. This device may be interfaced with phase-locked loop circuitry to reduce temperature drift to less than 250ppm/C.
