INA293B3IDBVT Frequently Asked Questions (FAQs)

  • The maximum voltage that can be applied to the input pins is 26.5V, which is the absolute maximum rating. However, for normal operation, the recommended maximum input voltage is 24V.
  • The gain error of the INA293 can be calculated using the formula: Gain Error (%) = (Vout / (Gain x Vin)) x 100, where Vout is the output voltage, Gain is the gain setting (1, 2, 4, or 8), and Vin is the input voltage.
  • The CAP pin is used to connect a capacitor to filter out high-frequency noise and oscillations. A 10nF to 100nF capacitor is recommended to be connected between the CAP pin and GND.
  • Yes, the INA293 can be used with a single-supply voltage. However, the input common-mode voltage range is limited to VCC - 2V to VCC + 0.1V, where VCC is the supply voltage.
  • The gain setting on the INA293 is selected by connecting the GAIN pin to VCC, GND, or leaving it open. The gain settings are: GAIN pin connected to VCC = Gain of 8, GAIN pin connected to GND = Gain of 1, and GAIN pin open = Gain of 2.
