INA185A3IDRLR Frequently Asked Questions (FAQs)

  • 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 within the common-mode voltage range of -0.2V to 26.4V.
  • The gain error of the INA185 can be calculated using the formula: Gain Error (%) = (Vout / (Gain x Vin)) - 1, where Vout is the output voltage, Gain is the gain setting (e.g. 1, 2, 5, or 10), and Vin is the input voltage.
  • The REF pin is a reference voltage output that can be used as a voltage reference for the system. It is internally connected to the output of a 1.2V bandgap voltage reference. The REF pin can be used as a voltage reference for ADCs, DACs, or other devices in the system.
  • Yes, the INA185 can be used as a differential amplifier with a gain of 1 by connecting the gain-setting resistors (Rg) to ground. This configuration is useful for applications that require a high-input impedance and a low-output impedance.
  • To minimize noise and EMI in the INA185 circuit, it is recommended to follow good PCB layout practices, such as keeping the input and output traces short and away from each other, using a ground plane, and placing bypass capacitors close to the device. Additionally, the INA185 should be placed close to the input signal source to minimize noise pickup.
