Description
The electronic circuit design like in Figure 1 above show you audio oscillator circuit using ICL8038. Other component need also that can supply with low voltage DC +10V and - 10V source to charge this IC and all system component from power supply built. With this electronic design circuit you can produce audio generator with 3 waves that useful now.
According Circuitstoday blog mentioned thatICL8038 is a monolithic waveform generator IC that can produce sine, square and triangular waveforms with very little distortion. The frequency can be programmed from 0.001Hz to 300 KHz using external timing capacitor and resistor. Frequency modulation and sweeping can be attained by using an external voltage. Other features of the ICL8038 are high linearity, high level outputs, simultaneous sine, square, triangle wave outputs, low external parts count, high temperature stability etc.
The working of ICL8038 is as follows. The external timing capacitor (C2 in the circuit diagram) is charged and discharged using two internal current sources. The first current source is on all the time and second current is switched ON and OFF using a flip-flop. Suppose the second current source is OFF and the first current source is ON, then the capacitor C2 will be charged with a continuous current (i) and the voltage across C2 increases linearly with time. When the voltage reaches 2/3 supply voltage, controlling flip flop is triggered and the first current source is activated. This current source carries double the current (2i) making the capacitor C2 is discharged with a current i and the voltage across it drops linearly with time. When this voltage reaches 1/3 supply voltage, the flip flop is resetted to the initial condition and the cycle is repeated again.

very useful- Thank you for writing it in a simple way, So that it is easy to understand.obsolete components distributor
ReplyDeletegood article about electronic design.To be honest,my physics is very poor, but this article helps me learn physics better.
