AD745–SPECIFICATIONS
Input offset voltage specifications are guaranteed after 5 minutes of operations at T
Test conditions: +V
Bias current specifications are guaranteed maximum at either input after 5 minutes of operation at T
Gain = –4, R
Defined as voltagc between inputs, such that neither exceeds 10 V from common.
The AD745 does not exhibit an output phase reversal when the negative common-mode limit is exceeded.
