For the AD7875, the temperature range for the K and L versions is from 0°C to +70°C; for the B and C versions is−40°C to +85°C; and for the T version is −55°C to
+125°C. For the AD7876, the temperature range for the B and C versions is from −40°C to +85°C and for the T version is−55°C to +125°C.
Includes internal reference error and is calculated after unipolar offset error (AD7875) or bipolar zero error (AD7876) has been adjusted out. Full-scale error refers to
both positive and negative full-scale error for the AD7876.
Dynamic performance parameters are not tested on the AD7876, but these are typically the same as for the AD7875.
SNR calculation includes distortion and noise components.
Sample tested @ +25°C to ensure compliance.
