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.
