7.6.4 Calibration
The CS5467 can perform gain and offset calibrations using either DC or AC signals. Proper input levels must
be applied to the current inputs and voltage input before performing calibrations.
CAL[5:4]* 00 = DC Offset
01 = DC Gain
10 = AC Offset
11 = AC Gain
CAL[3:0] 0001 = Current for Channel 1
0010 = Voltage for Channel 1
0100 = Current for Channel 2
1000 = Voltage for Channel 2
Note: Anywhere from 1 to all 4 channels can be calibrated simultaneously.
