INA2137UA/2K5 datasheet by Texas Instruments

INA2137UA/2K5 Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the INA2137UA/2K5?
  The maximum power dissipation of the INA2137UA/2K5 is 670mW at 25°C, but it can be derated to 500mW at 85°C.
• How do I layout the PCB to minimize noise and ensure optimal performance?
  To minimize noise and ensure optimal performance, it is recommended to use a 4-layer PCB with a solid ground plane, keep the input and output traces short and separate, and use a common-mode filter capacitor.
• What is the recommended input common-mode voltage range for the INA2137UA/2K5?
  The recommended input common-mode voltage range for the INA2137UA/2K5 is -200mV to +200mV, but it can operate up to ±250mV with reduced accuracy.
• Can I use the INA2137UA/2K5 in a high-temperature environment?
  Yes, the INA2137UA/2K5 can operate in a high-temperature environment up to 125°C, but the accuracy and linearity may degrade at higher temperatures.
• How do I calibrate the INA2137UA/2K5 for optimal performance?
  To calibrate the INA2137UA/2K5, apply a known input voltage and adjust the offset trim pin to zero the output, then adjust the gain trim pin to achieve the desired gain.
