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%/
o
C. A multivibrator (A
1
) generates pulses of constant
amplitude (V) and width (T
2
). Since the output (Terminal 6) of A
1
(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 (E
AVG
= V T
2
/T
1
) is applied to the non-
inverting input terminal of comparator A
2
(a CA5160) via an
integrating network R
3
, C
2
. Comparator A
2
operates to establish
circuit conditions such that E
AVG
= V
1
. This circuit condition is
accomplished by feeding an output signal from Terminal 6 of A
2
through R
4
, D
4
to the inverting terminal (Terminal 2) of A
1
,
thereby adjusting the multivibrator interval, T
3
.
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 SW
1
is ganged between input and
output circuitry to permit selection of the proper output voltage
for feedback to Terminal 2 via 10k
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
μ
A
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
μ
A.
