NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit

board with maintained transverse airflow greater than 500 lfpm. Electrical parameters are guaranteed only over the declared

operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit

values are applied individually under normal operating conditions and not valid simultaneously.

8. VEE can vary +0.25 V / −0.5 V.

9. VPP(min) is the minimum input swing for which AC parameters are guaranteed. The device has a DC gain of ≈ 40.
