Specifications subject to change without notice.
Specifications shown in boldface are tested on all production units at final electrical test. Results from those tests are used to calculate outgoing quality levels. All min and max

This is a measure of the deviation from ideal with a measuring thermocouple junction of 175 C and a chip temperature of 60 C. The ideal transfer function is given by:
Defined as the slope of the line connecting the AD596/AD597 CJC errors measured at 25 C and 100 C ambient temperature.
Pin 6 shorted to Pin 7.
Current Sink Capability in single supply configuration is limited to current drawn to ground through a 50 k resistor at output voltages below 2.5 V.
Alarm function available on H package option only.
