INA198AIDBVT datasheet by Texas Instruments

INA198AIDBVT Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the INA198AIDBVT can handle?
  The INA198AIDBVT can handle input voltages up to 80V, but it's recommended to limit the input voltage to 60V for optimal performance and reliability.
• How do I ensure accurate current measurements with the INA198AIDBVT?
  To ensure accurate current measurements, make sure to use a sense resistor with a low temperature coefficient, keep the sense resistor close to the INA198AIDBVT, and use a Kelvin connection to minimize parasitic resistances.
• What is the purpose of the VREF pin on the INA198AIDBVT?
  The VREF pin is used to set the internal reference voltage of the INA198AIDBVT. It can be connected to a voltage reference or a resistive divider to set the desired reference voltage.
• Can I use the INA198AIDBVT for high-side current sensing?
  Yes, the INA198AIDBVT can be used for high-side current sensing. However, it requires a voltage supply that is higher than the input voltage, and the sense resistor should be connected between the high-side of the load and the input voltage.
• How do I calculate the power dissipation of the INA198AIDBVT?
  The power dissipation of the INA198AIDBVT can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
