INA2137UA Frequently Asked Questions (FAQs)

  • The maximum power dissipation of the INA2137UA is 670mW at 25°C, but it can be derated to 500mW at 85°C.
  • To minimize noise and EMI, keep the input and output traces as short as possible, use a solid ground plane, and avoid routing signals near the device's pins. Also, use a low-ESR capacitor for the bypass capacitor (C1) and place it as close to the device as possible.
  • The recommended input common-mode voltage range for the INA2137UA is -200mV to +80mV, but it can operate up to ±250mV with reduced accuracy.
  • Yes, the INA2137UA can be used for high-side current sensing, but it requires an external voltage reference and a level-shifting circuit to shift the output voltage to the desired level.
  • The gain error of the INA2137UA can be calculated using the formula: Gain Error (%) = (Vout - (Vref x R2/R1)) / (Vref x R2/R1) x 100%, where Vout is the output voltage, Vref is the reference voltage, R1 and R2 are the gain-setting resistors.
