UCD3138A: UCD3138ARGCR

Part Number: UCD3138A

Tool/software:

Hi 

I was giving differential voltage output from the current sensor to the differential pins of EADC pins. I need to calculate total EADC error calculation for the microcontroller. Can you provide a formula to calculate the Total ADC error. and ADC count calculation.

 Part number :UCD3138ARGCR. 

And for the single ended ADC pin i Calculated the total error using the following formula. i would like to get the correct formula from your side.

DATASHEET Values

ADC12 INL integral nonlinearity, end point –3.9    ±2    4.5 LSB

ADC12 DNL differential nonlinearity(2)   –0.8/+2.4 LSB(Typical Value)

Formula,

TUE= SQRT (INL^2+DNL^2)
