Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 2: Supply current has a monotonic dependence on V
CC
(see
Typical Operating Characteristics
).
Note 3: IN leakage current has a monotonic dependence on V
CC
(see
Typical Operating Characteristics
).
Note 4: The MAX836 open-drain output can be pulled up to a voltage greater than V
CC
, but may not exceed 11V.
