The ICL8038 waveform generator is a monolithic integrated circuit capable of producing high accuracy sine, square, triangular, sawtooth and pulse waveforms with a minimum of external components. The frequency (or repetition rate) can be selected externally from 0.001Hz to more than 300kHz using either resistors or capacitors, and frequency modulation and sweeping can be accomplished with an external voltage.(Datasheet ICL8038)...Obsolete product but only use for students
Internal diagram of the oscillator
According to the data sheet can be used with two power supplies and a single power supply.
In my application Use only one power supply (12V), consumption of integrated circuit is very low (less than 20mA)
