INA199A1DCKR datasheet by Texas Instruments

INA199A1DCKR 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 ±40V, but it's recommended to keep it within ±20V for optimal performance.
• How do I calculate the gain of the amplifier?
  The gain of the amplifier is set by the ratio of the resistors R1 and R2. The gain can be calculated using the formula: Gain = (R2/R1) + 1.
• What is the purpose of the CAP pin?
  The CAP pin is used to connect a capacitor to filter out high-frequency noise and improve the stability of the amplifier. A 10nF to 100nF capacitor is recommended.
• Can I use the INA199A1DCKR as a differential amplifier?
  Yes, the INA199A1DCKR can be used as a differential amplifier by connecting the inputs differentially. However, the common-mode voltage range is limited to ±200mV.
• What is the power-on reset behavior of the INA199A1DCKR?
  The INA199A1DCKR has a power-on reset feature that ensures the output is in a high-impedance state during power-up. This prevents any output voltage from being present during startup.
