TYPICAL PERFOR A CE CHARACTERISTICS

ELECTRICAL CHARACTERISTICS

Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: Hysteresis current must be 500nA minimum. Hysteresis current

may exceed 50µA, but accuracy is not guaranteed.

resistor. See Applications Information for details.

Note 4: Determined by design, not production tested. External circuits

for ≥1µs.

Note 5: Internal circuits may drive the OUTn pins higher than the Absolute

Maximum Ratings.
