INA122U Frequently Asked Questions (FAQ)

  • The INA122U can handle input voltages up to ±40V, but it's recommended to keep the input voltage within ±20V for optimal performance.

  • The gain of the INA122U is determined by the ratio of the resistors Rg and Rf. The gain can be calculated using the formula: Gain = (Rf / Rg) + 1.

  • The REF pin is used to set the reference voltage for the amplifier. It can be connected to a voltage reference or a resistive divider to set the output voltage of the amplifier.

  • Yes, the INA122U can be used as a single-supply amplifier. However, the input voltage range will be limited to 0V to VCC, and the output voltage will be referenced to VCC/2.

  • To reduce noise and oscillations, ensure that the layout is clean and well-decoupled, use a low-ESR capacitor for power supply decoupling, and add a capacitor in parallel with Rf to reduce high-frequency noise.
