Hi team,
I found TCEG, TCEG Nonlinearity, TCEG Nonlinearity drift in the datasheet.
Could you show me the relationship among them? Could you show me an example characteristics between temperature vs gain error or TCEG?
Regards,
Ochi

Hi Ochi-san,
The transfer function for an ADC can be shown in terms of y=mx+b, where the x axis is the input voltage and the y axis is the corresponding output voltage. There are three main terms that describe the accuracy of this transfer function. Offset, gain, and nonlinearity. Each of these terms also have a corresponding drift specification to define how these terms change in response to changes in temperature.
Below shows an example transfer function.
From the AMC1302-Q1 datasheet:
TCEG stands for "temperature coefficient Error Gain" Also known as gain error drift. TCEG does not apply to nonlinearity and nonlinearity drift.
Please let me know if you have additional questions.
