Are input offset voltage and temperature drift the same each element?

Latest Updated:10/01/2009

Question:

Are the input offset voltage and temperature drift the same for each element in the operational amplifier IC incorporating multiple elements?

Answer:

The input offset voltage depends on the difference between VBE of the two transistors in the input differential circuit. Therefore the input offset voltage differs among the elements in the IC. The temperature drift also varies among the elements. For details of the temperature drift, see the VIO vs. TA characteristics graph in the data sheet.
