ICL8038 low and medium frequency signal source waveform sign

1. Overview
The LC ICL8038 module is designed for common frequency ranges. It is adjustable from 5 gears and generates low-distortion triangular waves, square and sine waves from 10Hz to 450KHz. Sine wave can be used for test signals, drive signals, carrier frequency signals, etc; square wave can be used for switching signals, trigger signals, etc; triangular wave is mainly used for scanning signals.
1. Introduced the hardware and instructions
1, Working voltage: 12V ~ 15V
2, Can output triangular wave, square wave and sine wave.
3, Frequency range: 10HZ ~ 450kHz
4, Low distortion sine wave: 1%
5, Duty cycle range: 2% to 98%
6, Low temperature drift: 50ppm / ℃
