NOTES:
6. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established
by characterization and are not production tested.
7. Parts are 100% tested with a minimum operating voltage of 1.65V to a VOS limit of ±15µV.
Typical Performance Curves V+ = 5V, V- = 0V, VCM = 2.5V, RL = Open.
