ICL8038 Sine / Rectangle / Triangle / Saw Waveform Generator Module
The ICL8038 is a classic - integrated monolithic function generator that enables the generation of basic electrical waveforms such as sine, rectangle, triangle (saw). It is ideal for amateur applications, as well as for simple applications in the electronic service. The ICL8038 module is designed for popular frequency ranges. It is adjustable from 5 frequency sub-ranges and generates low distortion triangle, square and sine waves from 10Hz to 450kHz. The sine wave can be used for test signals, drive signals, carrier frequency signals, etc., the square wave can be used for switching signals, trigger signals, clock signals, etc., and the triangle wave is mainly used for scanning signals.
