POWER REQUIREMENTS
As per AD7870
Refer to the power requirements in Table 1.
1 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 is40°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 is55°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.
