... Data Sheet Precision Waveform Generator/Voltage Controlled Oscillator 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 ...

... The Circuit of Figure 8 achieves this by using a diode to lower the effective supply voltage on the V- OR GND ICL8038. The large resistor on pin 5 helps reduce duty cycle variations with sweep. The linearity of input sweep voltage versus output frequency can be significantly improved by using an op amp as shown in Figure 10 ...
