shown in Equation 2-1.
EQUATION 2-1:
Changing the DUT’s bias voltages or ambient temperature changes V
application note AN1177 discusses in detail how these changes in V

• Specified Input Offset Voltage:
• DC Common Mode Rejection Ratio:
• DC Power Supply Rejection Ratio:
• DC Open-loop Gain:
• Input Offset Drift over Temperature:
