Supply current, 5 V
Conditions:
[1] With autozero on.
[2] Following an autocalibration at (23
[3] 100 s average.
[4] 0.1 Hz to 10 Hz.
[5] For a 100 pF source capacitance and an infinite source resistance.
Higher values of source capacitance or a finite source resistance will
degrade these specifications.
[6] Amphenol 31–10–4052 or similar.
[7] An overload will be detected and the instrument is not guaranteed
to perform properly if these limits are exceeded, or if V
exceeds the limits. Continuous application of a bias voltage V
excess of 15 V will damage the instrument.
[8] Tyco 227169–4 or similar.
[9] Rising-edge sensitive.
[10] External reference clock capture range. The instrument is not guar-
anteed to perform properly if these limits are exceeded.
[11] Non-condensing.
