AD8494/AD8495/AD8496/AD8497
SPECIFICATIONS
+VS = 5 V, −VS = 0 V, V+IN = V−IN = 0 V, VREF = 0 V, TA = TRJ = 25°C, RL = 100 kΩ, unless otherwise noted. Specifications do not include
gain and offset errors of the thermocouple itself. TA is the ambient temperature at the AD849x; TRJ is the thermocouple reference junction
temperature; TMJ is the thermocouple measurement junction temperature.
