"The NE/SE566 Function Generator is a voltage-controlled oscillator of exceptional linearity with buffered square wave and triangle wave outputs. The frequency of oscillation is determined by an external resistor and capacitor and the voltage applied to the control terminal. The oscillator can be programmed over a ten-to-one frequency range by proper selection of an external resistance and modulated over a ten-to-one range by the control voltage, with exceptional
linearity.

Features:

•Wide range of operating voltage (up to 24V; single or dual)
•High linearity of modulation
•Highly stable centre frequency (200ppm/°C typical)
•Highly linear triangle wave output
•Frequency programming by means of a resistor or capacitor, voltage or current
•Frequency adjustable over 10-to-1 range with same capacitor
