Electrical Characteristics

(1) (continued)

These specifications apply for V

− = GND = 0V, V+ = 5V, V

CM = VOUT = 2.5V, IR = 100 μA, FEEDBACK pin shorted to GND,

unless otherwise specified. Limits in standard typeface are for TJ = 25°C; limits in boldface type apply over the Operating

Temperature Range.

(5)

VR is the cathode-feedback voltage, nominally 1.244V.

(6)

Average reference drift is calculated from the measurement of the reference voltage at 25°C and at the temperature extremes. The drift,

in ppm/°C, is 106•

ΔVR/(VR[25°C]•ΔTJ), where ΔVR is the lowest value subtracted from the highest, VR[25°C] is the value at 25°C, and ΔTJ is

the temperature range. This parameter is ensured by design and sample testing.

(7)

Hysteresis is the change in VR caused by a change in TJ, after the reference has been “dehysterized”. To dehysterize the reference; that

is minimize the hysteresis to the typical value, its junction temperature should be cycled in the following pattern, spiraling in toward

25°C: 25°C, 85°C,

−40°C, 70°C, 0°C, 25°C.

(8)

Low contact resistance is required for accurate measurement.
