The devicecold junction compensates and amplifies a type J or K thermo- GND FB couple input to derive an internal signal proportional to tem- V­ perature. The internal signal is then compared with an externallyapplied setpoint voltage to yield a low impedance switched output SOIC voltage. Dead-Band or switching hysteresis can be programmedusing a single external resistor. Alternately, the AD596/AD597 can AD597 be configured to provide a voltage output (10 mV/°C) directly from +IN 1 8 ­IN a type J or K thermocouple signal. It can also be used as a stand- + ­ alone voltage output temperature sensor. G HYS 2 7 V+ The AD596/AD597 can be powered with a single supply from
