Product specification
Function generator
NE/SE566
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.
