Function Generator Circuit

Description.
The 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.This 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.
Notes .
  • The circuit needs a dual power supply . A +15 -15 power supply as shown in the circuit is enough for the purpose.
  • The frequency of the output wave form can be adjusted using R7.It must be a 100K Log POT.
  • The duty cycle can be adjusted using R3 , a 1K POT.
  • The distortion of the wave form can be adjusted using R5 , a 100K POT.
  • Square,triangle & sine waveforms can be obtained simultaneously at pins 9,3,2 respectively.
