INA330AIDGSTG4 Frequently Asked Questions (FAQs)

• What is the maximum voltage that can be applied to the input pins?
  The maximum voltage that can be applied to the input pins is 26.4V, which is the absolute maximum rating. However, for normal operation, the input voltage should be limited to the supply voltage (VCC) + 0.3V to ensure accurate measurements.
• How do I calculate the gain of the INA330?
  The gain of the INA330 is fixed at 20V/V. This means that the output voltage will be 20 times the input voltage. For example, if the input voltage is 1V, the output voltage will be 20V.
• What is the purpose of the REF pin?
  The REF pin is the reference voltage input for the INA330. It sets the output voltage zero point. Typically, it is connected to a voltage reference or a stable voltage source. The output voltage will be referenced to this voltage.
• Can I use the INA330 with a single-supply voltage?
  Yes, the INA330 can be used with a single-supply voltage. However, the input voltage range will be limited to 0V to VCC - 1.5V. For example, if VCC is 5V, the input voltage range will be 0V to 3.5V.
• What is the power-on reset behavior of the INA330?
  The INA330 has a power-on reset (POR) circuit that ensures the output is in a high-impedance state during power-up. When VCC reaches 1.5V, the POR circuit releases, and the output becomes active.
