INA125PA Frequently Asked Questions (FAQs)

  • The INA125PA can handle input voltages up to ±650mV, but it's recommended to keep the input voltage within ±500mV to ensure accurate measurements.
  • To ensure accurate gain and offset calibration, it's recommended to use a calibration resistor (Rcal) between the REF and REFOUT pins, and to follow the calibration procedure outlined in the datasheet.
  • The REF pin is the reference input for the amplifier, and the REFOUT pin is the output of the internal reference voltage. The REFOUT pin can be used as a reference voltage for other circuits in the system.
  • Yes, the INA125PA can be used as a single-ended amplifier by connecting the negative input (IN-) to a fixed voltage reference, such as ground or a voltage divider.
  • To minimize noise and interference, use proper PCB layout techniques, such as separating analog and digital grounds, using shielding, and keeping the input and output traces short and away from noise sources.
