Function Generator Using Icl8038 Pdf Apr 2026

: Created by passing the triangular wave through an internal non-linear wave-shaping network to "smooth" the peaks. Core Specifications Frequency Range : Typically 0.001 Hz to 300 kHz.

: Use the potentiometer between Pins 4 and 5 to ensure the triangle wave is perfectly linear and the square wave has a 50% duty cycle.

: Derived directly from the capacitor's linear voltage ramp.

The ICL8038 operates by charging and discharging an external capacitor with two internal current sources. This process creates a linear triangular wave.

: Monitor the sine wave on an oscilloscope and adjust the trimmers on Pins 1 and 12 until the waveform is smooth and rounded.

The is a precision waveform generator integrated circuit capable of producing high-accuracy sine, square, and triangular waveforms with a minimum of external components . Its versatility makes it a staple for signal generation in laboratories and electronic testing. Functional Overview

: Adjust the main potentiometer connected to Pin 8. The frequency ( ) is roughly calculated as

) : Connected to Pins 4 and 5 to control the charge/discharge current. : Frequency Control : Adjusts the current to Pin 8. Duty Cycle : Balances RAcap R sub cap A RBcap R sub cap B for symmetry. Distortion Trim : Two 100k Ωcap omega
