Figure 9. Low Droop Rate Sample and Hold—S2 improves
accuracy and acquisition time by including the voltage drop
across S1 inside the feedback loop. R1 closes the feedback
loop of A1 during the hold phase. The droop rate is [IBIAS(AZ)
+ ILEAK(S1) + ILEAK(S2)]/CHOLD.

Figure 10. Long-Time Constant Integrator—With RIN = 1011,
the time constant of this integrator is 100,000s. Since the input
voltage is converted to a current by RIN, the input voltage can
far exceed the power-supply range.

Figure 11. Pico Ammeter—The response time of this curcuit is
RFB x CFB, where CFB is the stray capacitance between the
output and the inverting terminal of the amplifier.
Figure 12. 60Hz Twin “T“ Notch Filter—The low 1pA bias cur-
rent of the ICL7611 allows use of small 540pF and 270pF
capacitors, even with a notch frequency of 60Hz. The 60Hz
rejection is approximately 40dB.
