HART Modem
ABSOLUTE MAXIMUM RATINGS
Voltage Range on All Pins (including AVDD,
Voltage Range on Any Pin Relative to
RECOMMENDED DC OPERATING CONDITIONS
(V
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 1: Specifications to -40°C are guaranteed by design and are not production tested.
Note 2: Active currents are measured when the device is driven by an external clock XCEN = 1 condition.
Note 3: Guaranteed by design and not production tested.
Note 4: Accuracy is guaranteed based on the external crystal or clock provided.
