ICL8038 12V to 15V Signal Generator 10Hz 450KHz Module

ICL8038 12V to 15V Signal Generator 10Hz 450KHz Module.

The ICL8038 Signal Generator Module is a function generator board capable of generating sine, square, and triangle waveforms over a wide frequency range of 10 Hz to 450 kHz.
It is based on the ICL8038 precision waveform generator IC, which offers low distortion, stable output, and adjustable frequency and amplitude.

The module includes onboard potentiometers to adjust frequency, duty cycle, and output amplitude, along with jumper/select pins to switch waveform types.
It is commonly used for testing audio circuits, analog filters, sensors, amplifiers, and educational experiments.

Operating voltage is typically 12V to 15V DC, suitable for lab bench use or electronics testing.
