: Derived directly from the capacitor's linear voltage ramp.
: Triangle wave linearity is approximately 0.1%. Function Generator Using Icl8038 Pdf
The ICL8038 operates by charging and discharging an external capacitor with two internal current sources. This process creates a linear triangular wave. : Derived directly from the capacitor's linear voltage ramp
) : 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 This process creates a linear triangular wave
: Single supply (10V to 30V) or dual supply ($\pm$5V to $\pm$15V). Key Components for the Circuit
: 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.
) : Connected between Pin 10 and ground; determines the frequency range. Timing Resistors (
