Note 1: Measure V (Pin 3) without input current for Pin 2. Force Pin 3 to
this measured voltage (which disables the preamp loop). Measure the
current into and out of Pin 3 when Pin 2 is driven.
Note 2: The gain is the differential voltage at the comparator inputs divided
by the differential voltage between the filter buffer output and VBIAS. This
parameter is not tested.
Note 3: Hysteresis is the difference in comparator trip point measured
when the output is high and when the output is low. This parameter is
not tested.
Note 4: Measure V (Pin 7) and V (Pin 9). Force these voltages to 200mV
below their nominal value to switch the comparators high.
Note 5: The current into Pin 11 is multiplied by 4 and then applied to a
500Ω resistor on the positive comparator inputs. The threshold is
I (Pin 11) • 4 • 500Ω.
