Having Trouble Finding a 150C Qualified Amplifier for Your Application?

Learn more about how our amplifiers may improve your products’ reliability and robustness.


Do your circuits need to work in automotive or industrial environments where high temperatures are prevalent due to proximity to the engine or other heat-generating components?

Here are some high temperature automotive applications.

  1. Turbocharger Systems: Turbochargers operate at high temperatures and require precise monitoring and control to optimize engine performance and efficiency.
  2. Exhaust Gas Recirculation (EGR) Systems: EGR systems help reduce emissions by recirculating a portion of the exhaust gases back into the engine cylinders.
  3. Fuel Injection Systems: Accurate control of fuel injection is critical for engine performance and emissions control.
  4. Brake Systems: Advanced braking systems, such as anti-lock braking systems (ABS) and electronic stability control (ESC), require precise sensor data to function effectively.
  5. Turbo Actuators and Wastegate Control: These components are part of the turbocharger system and require precise control to manage boost pressure.
  6. Catalytic Converter Monitoring: Catalytic converters operate at high temperatures to reduce harmful emissions.
  7. Thermal Management Systems: These systems manage the temperature of various vehicle components, including batteries in electric vehicles.
  8. HVAC Systems: Heating, ventilation and air conditioning (HVAC) systems in vehicles require precise control to maintain cabin comfort.
  9. Battery Management Systems (BMS): In hybrid and electric vehicles, BMS are critical for monitoring and managing battery health and performance.

Here are some industrial applications that may require amplifiers capable of operating at temperatures up to 150°C.

  1. Industrial Motor Control: Motors used in industrial machinery often operate in high-temperature environments. Amplifiers are used in current sensing and feedback loops to ensure precise motor control, efficiency and protection against overheating.
  2. Power Supply Monitoring: Industrial power supplies can generate significant heat, especially in high-power applications. Amplifiers are used to monitor voltage and current levels, ensuring stable and efficient power delivery.
  3. Process Control Systems: In industries such as chemical processing, oil and gas and food production, process control systems require precise monitoring of temperature, pressure and flow.
  4. Robotics and Automation: Automated systems and robots often operate in environments with fluctuating temperatures.
  5. Industrial HVAC Systems: Heating, ventilation and air conditioning systems in industrial facilities require accurate temperature and pressure monitoring to maintain optimal environmental conditions.
  6. Renewable Energy Systems: Solar power inverters and wind turbine control systems operate in varying temperature conditions.
  7. Industrial Lighting Systems: High-intensity lighting systems, such as those used in manufacturing plants and warehouses, generate significant heat.
  8. Test and Measurement Equipment: Equipment used for testing and measuring industrial processes often operates in high-temperature environments.
  9. Industrial Safety Systems: Safety systems, such as fire detection and suppression systems, require reliable operation in high-temperature conditions.
  10. Oil and Gas Exploration: Exploration and drilling equipment in the oil and gas industry are exposed to extreme temperatures.

These applications highlight the diverse range of automotive and industrial applications that can benefit from high-temperature amplifiers, ensuring reliable performance and accurate data processing in challenging thermal environments.

We have a portfolio of AEC-Q100 Grade 0 qualified operational amplifiers (op amps) and current sense amplifiers (CSA), designed to operate in temperatures ranging from -40°C to 150°C. This high-temperature rating ensures that our amps can withstand the harshest environments, providing unparalleled performance and reliability where it matters most. For more 150C rated amplifier product information, please see Microchip’s AEC-Q100 Grade 0 (150C) Qualified Amplifiers blog post.
