GAIN CALIBRATION REGISTERS (GAIN_CALx)

DETAILS

The gain calibration registers contain the measured gain

error of each individual ADA4254. Refer to the Gain Error

Calibration section for details on how to use these values.

GAIN_CAL1 through GAIN_CAL12 store gain error results

for each input gain setting with a scaling gain of 1 V/V. When a

scaling gain of 1 V/V is used, these gain error values are used

directly. GAIN_CAL13 through GAIN_CAL24 store any

additional gain error incurred when 1.375 V/V or 1.25 V/V

scaling gains are used. When scaling gains other than 1 V/V are

used, the gain error read from the appropriate GAIN_CAL1

through GAIN_CAL12 register must be summed with the

corresponding additional gain error read from the appropriate

GAIN_CAL13 through GAIN_CAL24. For example, if the

input gain is 2 V/V and the 1.25 V/V scalar is used, the total

gain error is GAIN_CAL6 + GAIN_CAL21.
