constant to insure constant reverse voltage bias on the
photo diode.
Low-Frequency Multivibrator
In this application, one half of the CA3290 is used as a
conventional multivibrator circuit. Because of the extremely
high input impedance of this device, large values of timing
resistor (R1) may be used for long time delays with relatively
small leakage timing capacitors. The second half of the
CA3290 is used as an output buffer to insure that the
multivibrator frequency will not be affected by output loading.
RP is the parallel combination of the two 1MΩ resistors
connected between +15V and GND.
Window Comparator
Both halves of the CA3290 can be used in a high input
impedance window comparator as shown in Figure 7. The
LED will be turned “on” whenever the input signal is above
the lower limit (VL) but below the upper limit (VU), as
determined by the R1/R2/R3 resistor divider.
