DESCRIPTION

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.
