NOTES
1
Calibrated for minimum error at +25癈 using a thermocouple sensitivity of 51.7 礦/癈. Since a J type thermocouple deviates from this straight line approximation, the AD594 will normally
read 3.1 mV when the measuring junction is at 0癈. The AD595 will similarly read 2.7 mV at 0癈.

Defined as the slope of the line connecting the AD594/AD595 errors measured at 0癈 and 50癈 ambient temperature.

INTERPRETING AD594/AD595 OUTPUT VOLTAGES
To achieve a temperature proportional output of 10 mV/癈 and
accurately compensate for the reference junction over the rated
operating range of the circuit, the AD594/AD595 is gain trimmed
to match the transfer characteristic of J and K type thermocouples
at 25癈. For a type J output in this temperature range the TC is
51.70 礦/癈, while for a type K it is 40.44 礦/癈. The resulting
gain for the AD594 is 193.4 (10 mV/癈 divided by 51.7 礦/癈)
and for the AD595 is 247.3 (10 mV/癈 divided by 40.44 礦/癈).
In addition, an absolute accuracy trim induces an input offset to
the output amplifier characteristic of 16 礦 for the AD594 and
11 礦 for the AD595. This offset arises because the AD594/
AD595 is trimmed for a 250 mV output while applying a 25癈
thermocouple input.
Because a thermocouple output voltage is nonlinear with respect
to temperature, and the AD594/AD595 linearly amplifies the
compensated signal, the following transfer functions should be
used to determine the actual output voltages:
AD594 output = (Type J Voltage + 16 ?/SPAN>V) ?/SPAN> 193.4
AD595 output = (Type K Voltage + 11 ?/SPAN>V) ?/SPAN> 247.3 or conversely:
Type J voltage = (AD594 output/193.4) 16 ?/SPAN>V
Type K voltage = (AD595 output/247.3) 11 ?/SPAN>V
Table I lists the ideal AD594/AD595 output voltages as a func-
tion of Celsius temperature for type J and K ANSI standard
thermocouples, with the package and reference junction at
25癈. As is normally the case, these outputs are subject to cali-
bration, gain and temperature sensitivity errors. Output values
for intermediate temperatures can be interpolated, or calculated
using the output equations and ANSI thermocouple voltage
tables referred to zero degrees Celsius. Due to a slight variation
in alloy content between ANSI type J and DIN FE-CUNI
