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.
