NE566F

Philips Semiconductors Linear Products 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.

The circuit provides simultaneous square wave and triangle wave outputs at frequencies up to 1MHz. A typical connection diagram is shown in Figure 1. The control terminal (Pin 5) must be biased externally with a voltage (VC) in the range V+≤VC≤V+ where VCC is the total supply voltage. In Figure 1, the control voltage is set by the voltage divider formed with R2 and R3. The modulating signal is then AC coupled with the capacitor C2. The modulating signal can be direct coupled as well, if the appropriate DC bias voltage is applied to the control terminal. The frequency is given approximately by fO + 2 [(V )) * (V C)] R1 C1 V ) and R1 should be in the range 2kΩ< R1
