(1) On products compliant to MIL-PRF-38535, this parameter is not production
tested.
(2) Full range is –55°C to 125°C.
(3) The deviation parameters VI(dev) and II(dev) are
defined as the differences between the maximum and minimum values obtained over the rated
temperature range. The average full-range temperature coefficient of the reference input
voltage αVI(ref) is defined as:
αVI(ref) is positive or negative, depending on whether minimum VI(ref) or maximum VI(ref), respectively, occurs at the lower temperature.
αVI(ref) is positive or negative, depending on whether minimum VI(ref) or maximum VI(ref), respectively, occurs at the lower temperature.
(4) The output impedance is defined as:
When the device is operating with two external resistors (see Figure 7-2), the total dynamic impedance of the circuit is given by:
, which is approximately equal to
