The quoted values of Vref are based on a constant current IZ. Two factors can cause Vref to change with IZ, namely the differential resistance rdif and the temperature coefficient SZ. a) Each change of IZ can result in a maximum change of Vref as follows: Vref (mV) = IZ (mA) x 15 taking into account that rdif is max. 15 . b) The temperature coefficient of the reference voltage SZ is also a function of IZ. However, for these reference diodes SZ varies max. 0.05 mV/K or 0.001%/K when IZ is between 6 and 10 mA, so this effect can be neglected in practice for these types. 2. The temperature coefficient of the reference voltage is obtained from the following formula: V ref1 - V ref2 100 S Z = ------------------------------------- x ------------------- %/K T amb2 - T amb1 V ref nom THERMAL CHARACTERISTICS SYMBOL Rth j-tp Rth j-a Note 1.

DEFINITIONS Data Sheet Status Objective specification Preliminary specification Product specification Limiting values Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability. Application information Where application information is given, it is advisory and does not form part of the specification. LIFE SUPPORT APPLICATIONS These products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be expected to result in personal injury. Philips customers using or selling these products for use in such applications do so at their own risk and agree to fully indemnify Philips for any damages resulting from such improper use or sale. This data sheet contains target or goal specifications for product development. This data sheet contains preliminary data; supplementary data may be published later. This data sheet contains final product specifications. 1996 Mar 21 4 |
