INA849DGKR Frequently Asked Questions (FAQs)

  • The maximum voltage that can be applied to the input pins is ±40V, but it's recommended to keep it within ±20V for optimal performance.
  • To ensure accurate measurements, make sure to use a high-impedance input source, keep the input voltage within the recommended range, and use a low-noise power supply. Also, consider using a filter capacitor on the input pins to reduce noise.
  • The REF pin is a reference voltage output that can be used as a voltage reference for the system. It's typically connected to the analog-to-digital converter (ADC) reference input or used as a voltage reference for other components in the system.
  • Yes, the INA849 can be used with a single-supply voltage. However, the input common-mode voltage range is limited to VCC - 1.5V to VCC + 0.5V. Make sure to check the datasheet for specific voltage ranges and limitations.
  • The gain of the INA849 is determined by the ratio of the resistors connected to the RG pins. The gain can be calculated using the formula: Gain = (R2/R1) x (1 + R4/R3), where R1, R2, R3, and R4 are the resistors connected to the RG pins.
