Precision Quadrature Oscillator

4423

FEATURES

DESCRIPTION

The Model 4423 is a precision quadrature oscillator. It

has two outputs 90 degrees out of phase with each

other, thus making sine and cosine wave outputs

available at the same time. The 4423 is resistor-

programmable and is easy to use. It has low distortion

(0.2% max up to 5kHz) and excellent frequency and

amplitude stability.

The Model 4423 also includes an uncommitted

operational amplifier that may be used as a buffer, level

shifter, or as an independent operational amplifier. The

4423 is packaged in a versatile, small, low-cost DIP

package.
