Note 3:Operating ratings indicate conditions for which the device is intended to be functional, but may not meet the guaranteed specific performance limits. For guar- anteed specifications and conditions, see the Electrical Characteristics. Note 4:Tested per VR Sensor Interface test circuit. See figures 8 and 9. Note 5:Minimum Detect Current is not production tested at +85C. Specifications is guaranteed through device characterization and Test Limits at 25˚C and 125˚C.
