ICL8038CCPD Precision Waveform Generator or Voltage Controlled Oscillator IC

ICL8038CCPD Precision Waveform Generator or Voltage Controlled Oscillator IC designed as  a monolithic integrated circuit capable of generating high accuracy sine, square, triangular, sawtooth and pulse waveforms with a minimum of external components. The frequency/repetition rate selected externally from 0.001Hz to more than 300kHz using either resistors or capacitors. And also frequency modulation and sweeping achieved with an external voltage. The ICL8038 IC 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. Moreover, this IC features low distrotion and high linearity offering a high-level voltage output. This IC operates at a duty cycle of 2% to 98% with a supply range of 10V to 30V.

A waveform generator belongs to a signal generator used to generate electrical waveforms over a wide range of signals. Common types of waveforms outputs include sine wave, square wave, ramp or triangular wave, pulse wave, cardiac pattern wave, gaussian pulse waves, arbitrary waves. Moreover, these waveforms can be injected into a test circuit and analyzed to confirm the device is operating properly.

Voltage-controlled oscillator designed as a type of oscillator where the frequency of the output oscillations varied by varying the amplitude of an input voltage signal. Voltage-controlled oscillators widely used in frequency (FM), pulse (PM) modulators, and phase-locked loops (PLL). These broadly classified into a linear voltage-controlled oscillator and relaxation type voltage-controlled oscillators.
