ICL8038 is a function generator chip, able of generating triangular, square , sine, pulse and sawtooth waveforms . From these sine, square & triangular wave forms can be made simultaneously. There is the option to control the parameters like frequency ,duty cycle and distortion of these functions. rangkian pembangkit gelombang ini is the best function generator circuit for a beginner to start with and is of course a must on the work bench of an electronics hobbyist. The circuit here is designed to produce waveforms from 20Hz to 2o kHz.The ICL 8038 has to be operated from a dual power supply.

Circuit Diagram & Parts List of Function Generator on show in the picture below.

Notes .

  • frequency output can be adjusted using R7.It must be a 100K Log POT.
  • The duty cycle can be adjusted using R3 , a 1K POT.
  • Distortion owave form can be adjusted using R5 , a 100K POT.
  • Square,triangle & sine waveforms can be obtained simultaneously at pins 9,3,2 respectively.
Datasheet ICL 8038

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. These devices may be interfaced with phase locked loop circuitry to reduce temperature drift to less than 250ppm/oC.
