Product Overview

The AD8494CRMZ is a precision Instrumentation Amplifier with thermocouple cold junction compensators on an integrated circuit. They produce a high level (5mV/°C) output directly from a thermocouple signal by combining an ice point reference with a pre-calibrated amplifier. The device is pre-calibrated by laser wafer trimming to match the characteristics of J type (iron-constantan) thermocouples. The device can be powered from a single-ended supply (less than 3V) and can measure temperatures below 0°C by offsetting the reference input. To minimize self-heating, an unloaded device typically operates with a total supply current of 180μA, but it is also capable of delivering in excess of ±5mA to a load. With a 5V single supply, the 5mV/°C output allows the devices to cover nearly 1000 degrees of a thermocouple's temperature range.
  • High impedance differential input
  • Standalone 5mV/°C Thermometer
  • Reference pin allows offset adjustment
  • Thermocouple break detection
  • Laser wafer trimmed to 1°C initial accuracy and 0.025°C/°C ambient temperature rejection
