AD8494…AD8497 Thermocouple Amplifiers, Analog Devices

A range of dedicated thermocouple amplifiers from Analog Devices. These integrated devices incorporate precision instrumentation amplifiers and thermocouple cold junction compensation to provide a high level output directly from a type J or K thermocouples.

The following versions are available:
AD8494 for type J thermocouples, optimised operating temperature range 0°C to 50°C
AD8495 for type K thermocouples, optimised operating temperature range 0°C to 50°C
AD8496 for type J thermocouples, optimised operating temperature range 25°C to 100°C
AD8497 for type K thermocouples, optimised operating temperature range 25°C to 100°C
All versions have a measurement range equal to the full range of the relevant thermocouple type.

• Low cost and easy to use
• Can be used as a stand-alone 5 mV/°C thermometer
• Pre-trimmed for J or K type thermocouples to 1°C initial accuracy
• Wide power supply range: 2.7 to 36V or ±2.7 to ±18V
• Internal cold junction compensation
• High impedance differential inputs
• Thermocouple break detection
