INA105KU Frequently Asked Questions (FAQ)

  • The INA105KU can handle input voltages up to ±650mV, but it's recommended to keep the input voltage within ±500mV to ensure accurate measurements.

  • To ensure accuracy, make sure to follow proper PCB layout and grounding techniques, use a low-noise power supply, and minimize electromagnetic interference (EMI) in the surrounding environment.

  • The REF pin is used to set the reference voltage for the INA105KU's internal amplifier. It's typically connected to a stable voltage reference or a voltage divider to set the desired gain.

  • The INA105KU is suitable for applications up to 100 kHz. However, for higher frequency applications, it's recommended to use a more specialized instrumentation amplifier like the INA826 or INA827.

  • The gain of the INA105KU can be calculated using the formula: Gain = (Rgain / Rg) + 1, where Rgain is the gain resistor and Rg is the gain-setting resistor.
