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.

/C0052/C0052/C0050/C0051 SBFS020A − JANUARY 1978 − REVISED JUNE 2004 www.ti.com This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

There are various types of capacitors available for use. of capacitor types is shown in Table 2. Table 2. Comparison of Nonpolarized Capacitors normally have to be added to the 4423 specifications. any capacitors with dissipation factors greater than 1%. Such capacitors would stop 4423 oscillation. resistor R is given by Equation (4).

/C0052/C0052/C0050/C0051 SBFS020A − JANUARY 1978 − REVISED JUNE 2004 www.ti.com For example, the DF of ceramic disc capacitors is on the order of 3%, which for a 0.01µF capacitor would be comparable to an internal resistor of 530kΩ at 1kHz. The 530kΩ value resistor is small enough to stop the 4423 oscillator from oscillating. Some capacitor manufacturers use the terms Power Factor (PF) or Q Factor (Q) instead of dissipation factor. These terms are similar in meaning and are mathematically related by Equations (5) and (6). (PF)/C0043(DF) 1 /C0041(DF)2/C0504 Q /C00431 (DF) OSCILLATION AMPLITUDE It takes a finite time to build up the amplitude of the oscillation to its final full-scale value. There is a relationship between the amplitude build-up time and the frequency. The lower the frequency, the longer the amplitude build-up time. For example, it typically takes 250 seconds at 1Hz, 30 seconds at 10Hz, 4 seconds at 100Hz, 400 milliseconds at 1kHz, and 40 milliseconds at 10kHz oscillator frequencies. There are two methods available to shorten this normal amplitude build-up time. There is also a relationship between the amplitude build-up time and distortion at final amplitude value. When the amplitude build-up time is shortened, the distortion can become worse. One method to shorten the amplitude build-up time is to connect a resistor between pin 3 and pin 14. The lower the value of this resistor, the shorter the time to build up amplitude of the oscillation. Conversely, the distortion of the output waveform worsens. For example, a 100kΩ resistor would shorten the amplitude build-up time, from 15 seconds to 1 second at 20kHz frequency, but the distortion could be degraded from typically 0.05% to 0.5%. The other method is to momentarily insert a 1kΩ resistor via a reset switch between pin 3 and pin 14. The amplitude of oscillation is built up instantaneously when the reset switch is pushed. There will be no degradation of distortion with this method since the 1kΩ resistor does not remain in the circuit continuously. (5) (6)
