Product Overview

The AD8495ARMZ is a precision thermocouple amplifier with cold junction compensation in 8 pin MSOP package. It produces high level (5mV/°C) output directly from thermocouple signal by combining an ice point reference with pre-calibrated amplifier. This device can be used as standalone thermometer or as switched output setpoint controller using either fixed or remote setpoint control. The AD8495A can be powered from single ended supply (less than 3V) and can measure temperatures below 0°C by offsetting the reference input. To minimize self heating, an unloaded AD8495A typically operates with total supply current of 180μA and it is also capable of delivering in excess of ±5mA to a load. The AD8495A is laser trimmed to match the characteristics of K type (chromel alumel) thermocouples.
  • Low cost and easy to use
  • Pretrimmed for K type thermocouple
  • Optimized ambient temperature (reference junction) from 0°C to 50°C
  • High impedance differential input
  • Reference pin allows offset adjustment
  • Thermocouple break detection
  • Temperature accuracy of 3°C
  • Low power of less than 1mW at VS = 5V
  • Single supply voltage from 2.7V to 36V and dual supply range from ±2.7V to ±18V
  • Operating temperature range from -40°C to 125°C

Applications
