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. 2 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. 3 Dynamic performance parameters are not tested on the AD7876, but these are typically the same as for the AD7875. 4 SNR calculation includes distortion and noise components. 5 Sample tested @ +25°C to ensure compliance. |
