10 / 19 page 10 Precision Voltage-Controlled Oscillator The circuit diagram of a precision voltage-controlled oscillator is shown in Figure 10. The oscillator operates with a tracking error on the order of 0.02% and a temperature coefficient of 0.01%/oC. A multivibrator (A1) generates pulses of constant amplitude (V) and width (T2). Since the output (Terminal 6) of A1 (a CA5130) can swing within about 10mV of either supply-rail, the output pulse amplitude (V) is essentially equal to V+. The average output voltage (EAVG =V T2/T1) is applied to the non-inverting input terminal of comparator A2 (a CA5160) via an integrating network R3, C2. Comparator A2 operates to establish circuit conditions such that EAVG = V1. This circuit condition is accomplished by feeding an output signal from Terminal 6 of A2 through R4, D4 to the inverting terminal (Terminal 2) of A1, thereby adjusting the multivibrator interval, T3. Voltmeter With High Input Resistance The voltmeter circuit shown in Figure 11 illustrates an application in which a number of the CA5160 characteristics are exploited. Range-switch SW1 is ganged between input and output circuitry to permit selection of the proper output voltage for feedback to Terminal 2 via 10k Ω current-limiting resistor. The circuit is powered by a single 8.4V mercury battery. With zero input signal, the circuit consumes somewhat less than 500 µA plus the meter current required to indicate a given voltage. Thus, at full-scale input, the total supply current rises to slightly more than 1500 µA. 6 7 3 4 2 +15V 0.01 µF 10k Ω + - 0.1 µF 1 5 2k Ω OFFSET ADJUST 100k Ω FIGURE 7A.
