Function Generator Using Icl8038 Pdf Apr 2026

: 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.

) : Connected between Pin 10 and ground; determines the frequency range. Timing Resistors (

: 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.

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

: Generated by a flip-flop driven by the charging/discharging cycles.

potentiometers at Pins 1 and 12 to minimize sine wave harmonics. Pin 1 & 12 : Sine wave adjustment (distortion). Pin 2 : Sine wave output. Pin 3 : Triangle wave output. Pin 4 & 5 : Duty cycle/Frequency adjustment. Pin 8 : Frequency sweep input. Pin 9 : Square wave output. Pin 10 : Timing capacitor. Step-by-Step Calibration

: Triangle wave linearity is approximately 0.1%.
