The AD594AD from Analog Devices is a complete instrumentation amplifier and thermocouple cold junction compensator integrated onto a single monolithic chip. It combines an ice point reference with a precalibrated amplifier to deliver a high-level output of 10mV/°C directly from a thermocouple signal.
This device is pretrimmed for Type J (AD594) or Type K (AD595) thermocouples and can also be used with Type T inputs. It features a wide power supply range from +5V to ±15V and operates across a broad temperature range of -55°C to 125°C. The AD594AD includes a thermocouple failure alarm and can be configured for setpoint mode operation or as a self-contained Celsius thermometer.
Available in a 14-pin CDIP package, the AD594AD is designed for through-hole mounting. Its high impedance differential input helps reject common-mode noise, making it suitable for accurate temperature measurements in various applications. The laser wafer trimming ensures a calibration accuracy of typically ±1°C.
