Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2: All Currents into device pins are positive and all currents out

of device pins are negative. All voltages are referenced to VEE unless

otherwise specified.

Note 3: When VZ is connected to VIN, an internal shunt regulator limits the

voltage to a minimum of 11V. Driving the pins above 11V may damage the

part. These pins can be safely biased by a higher voltage using a resistor

or current source that limits the current below 50mA.

Note 4: An internal clamp limits DRAIN to a minimum of 3.2V. Driving

this pin to voltages above the clamp may damage the part. The pin can

be safely tied to higher voltages through a resistor that limits the current

below 1.5mA.

Note 5: An internal clamp limits EN# to a minimum of 6V. Driving this pin

to voltages above the clamp may damage the part. The pin can be safely

tied to higher voltages through a resistor that limits the current below 5mA.

Note 6: Guaranteed by design and characterization. Not tested in

production.

Note 7: Tested at 12-bit resolution and guaranteed for other resolutions by

design and characterization.

Note 8: EEPROM endurance and retention are guaranteed by design,

characterization and correlation with statistical process controls.

Note 9: EEPROM endurance and retention will be degraded when TJ > 85°C.
