1. The ICL8038 is an integrated precision oscillator circuit with multiple waveform outputs. The frequency and duty cycle of the output waveform can be controlled by current or resistance. Since the chip features an input for a frequency modulation signal, it can be widely applied. 2. A low frequency drift occurs with temperature changes, with a maximum drift not exceeding 50 ppm/°C. It provides sine wave, triangular wave, rectangular wave, and other functional signal outputs. The sine wave output distortion is less than 1%. 3. This module is designed for a universal frequency range. It can be adjusted to 5 ranges and generates lowdistortion sine, triangular, square, and other pulse waves within the range of 10 Hz to 450 kHz. 4. Sine waves can be used for test signals, control signals, carrier frequency signals, etc. Rectangular waves are suitable for switching signals, trigger signals, etc. Triangular waves are primarily used for scanning signals.
