ADJUSTABLE MICROPOWER VOLTAGE REFERENCE DIODE

Advanced Monolithic Systems Inc 

AMS285/AMS385

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the

device is intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical

Characteristics. The guaranteed specifications apply only for the test conditions listed.

Note 2: For elevated temperature operation, Tj max is:

AMS285

AMS385

+125°C

+100°C

Thermal Resistance

TO-92

ϕ JA (junction to ambient) 170°C/W (0.125” leads)

SO-8

165°C/W

SOT-89

160°C/W

Note 3: Parameters identified with boldface type apply at temperature extremes. All other numbers apply at TA = TJ = 25°C.

Note 4: Guaranteed and 100% production tested.

Note 5: Guaranteed but not 100% production tested. These limits are not used to calculate average outgoing quality levels.

Note 6: The average temperature coefficient is defined as the maximum deviation of reference voltage at all measured temperatures between the operating

TMAX and TMIN, divided by TMAX - TMIN. The measured temperatures are 0°C, 25°C, 70°C and 85°C.
