AD594 - Monolithic Thermocouple Amplifiers with Cold Junction Compensation

General Description

The AD594/AD595 is a complete instrumentation amplifier and thermocouple cold junction compensator on a monolithic chip.

It combines an ice point reference with a precalibrated amplifier to produce a high level (10 mV/°C) output directly from a thermocouple signal.

Key Features

  • Pretrimmed for Type J (AD594) or Type K (AD595) Thermocouples Can Be Used with Type T Thermocouple Inputs Low Impedance Voltage Output: 10 mV/؇ C Built-In Ice Point Compensation Wide Power Supply Range: +5 V to ؎15 V Low Power:.
