OPERATING MODES

Rev A1, Page 16/29

In order to calibrate iC-MSA, compensate for the input

signals and test iC-MSA the mode of operation must

be changed. The output function changes according

to the various operating modes; the line drivers and

protection against reverse polarity facility are only ac-

tive in normal mode.

Calibration Op. Modes

In Calibration Mode 1 the user can measure the BIAS

current (IBN), input ampliï¬er reference potential VREFI

and the analog signals from channel 0 following signal

conditioning (PCH0 and NCH0).

In Calibration Mode 2 the conditioned signals from

channels 1 and 2 are output (PCH1, NCH1, PCH2 and

NCH2).

In Calibration Mode 3 the internal temperature moni-

toring signals are provided.

Special Device Test Functions

IDDQ-Test, Saturation Low, Saturation High, and Test

1 to 5 are test modes for iC-Haus device tests. With an

activated bypass (BYP = 1), mode iC-Haus Test 4 per-

mits the direct feedthrough of X1 - X6 input signals to

the output pins; in this instance the output impedance

is high-ohmic. Furthermore, if the input voltage divider

is selected (by RINx = 1- -1), it reduces the signal am-

plitudes to approx. 7/8.

Signal Filter

iC-MSA has a noise limiting signal ï¬lter to ï¬lter the con-

ditioned analog signals. This can be activated using

ENF.
