Assumes use of external components as shown in the application diagram (Figs 38 or 39).
Highest clock frequency at which data slicer produces 1010 output in analog self-test mode.
The maximum input current depends on the value of the external resistor connected to I
ref
and the settings of shadow
registers A and C:
a) With R
Iref
= 30 k

where:
a) Digital output = the number of pulses at the digital output in counts/s and I

and on shadow registers A and C.
c) The gain tolerance is the deviation from the calculated gain.
