Description

The AD595 is a monolithic integrated circuit that amplifies the small voltage output from a thermocouple and provides a high-level analog voltage output that is proportional to temperature. It includes built-in cold junction compensation, which corrects for the temperature at the thermocouple’s reference junction. This IC is designed for precision temperature measurement applications and is factory-calibrated for use with Type K thermocouples.

Features

  • Thermocouple Interface: Designed specifically for Type K thermocouples but can be adapted for other types.
  • Cold Junction Compensation: Automatically compensates for the temperature of the reference junction, ensuring accurate temperature readings.
  • High-Level Output Voltage: Outputs a 10 mV/°C signal, making it easy to interface with ADCs or microcontrollers.
  • Wide Temperature Range: Supports temperature measurements over a wide range, typically -200°C to +1250°C for Type K thermocouples.
  • Factory-Calibrated: Calibrated to provide accurate temperature readings without the need for additional calibration in most applications.
  • Low Power Consumption: Operates with minimal power, making it suitable for battery-powered applications.
  • Simple to Use: Requires minimal external components, simplifying circuit design.

Specifications

  • Input Type: Type K thermocouple (can be used with other types with appropriate modifications).
  • Output Voltage: 10 mV/°C (e.g., 250 mV for 25°C).
  • Temperature Range: -200°C to +1250°C (for Type K thermocouples).
  • Accuracy: Typically ±1°C to ±2°C depending on the operating temperature range.
  • Supply Voltage: 5V to 30V.
  • Supply Current: Typically 160 µA.
  • Operating Temperature Range: -55°C to +125°C.
  • Package Type: Available in DIP, SOIC, and TO-99 packages.

Applications

  • Temperature Monitoring: Used in systems where accurate temperature measurement is crucial, such as industrial processes, HVAC systems, and environmental monitoring.
  • Thermocouple Signal Conditioning: Amplifies and conditions the small signal from a thermocouple for further processing.
  • Temperature Control Systems: Used in feedback loops to control heating or cooling systems based on precise temperature readings.
  • Laboratory Instruments: Ideal for use in precision temperature measurement equipment in scientific research.
  • Home Appliances: Can be used in appliances like ovens and water heaters that require accurate temperature control.
