ICL8038N

HGSEMI · Operational Amplifier · DIP-14

ICL8038N from HGSEMI, in a DIP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 SINE WAVE ADJ input Sine wave distortion adjust. External potentiometer between this pin and V- trims the sine wave symmetry/distortion.
2 SINE WAVE OUT output Sine wave output. Low-impedance analog waveform output, typical amplitude 0.22 x (V+ - V-).
3 TRIANGLE OUT output Triangle wave output. Analog output, amplitude typically 0.33 x (V+ - V-).
4 DUTY CYCLE/FREQ ADJ A input Duty cycle / frequency adjust input A. Timing resistor RA sets the rising slope current of the timing capacitor.
5 DUTY CYCLE/FREQ ADJ B input Duty cycle / frequency adjust input B. Timing resistor RB sets the falling slope current; combined with RA controls duty cycle from 2% to 98%.
6 V+ power_in Positive supply. Single supply +10 V to +30 V, or dual supply +/-5 V to +/-15 V.
7 FM BIAS output FM bias voltage. Internal reference used to set the nominal frequency; can be connected to pin 8 for basic (non-swept) operation.
8 FM SWEEP IN input FM sweep / VCO control input. Applying a voltage relative to V+ modulates the output frequency for FM or sweep operation.
9 SQUARE WAVE OUT output Square wave output. Open-collector output; requires an external pull-up resistor to V+ (or to a separate supply for level shifting).
10 TIMING CAP passive Timing capacitor connection. External capacitor C from this pin to V- sets the operating frequency together with RA and RB.
11 V-/GND power_in Negative supply / ground. Connect to ground for single-supply operation or to the negative rail for dual-supply operation.
12 SINE WAVE ADJ input Sine wave distortion adjust (second tap). Companion to pin 1 for full symmetry trim of the sine shaper.
13 NC unconnected No internal connection.
14 NC unconnected No internal connection.
