INA129UA/2K5E4 Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the INA129UA/2K5E4 is ±650mV, which is the maximum differential input voltage. Exceeding this voltage can cause damage to the device.

  • To ensure accurate measurements, it's essential to follow proper layout and grounding techniques, use a low-noise power supply, and minimize electromagnetic interference (EMI) and radio-frequency interference (RFI) in the circuit. Additionally, use a high-precision voltage reference and ensure that the input signals are within the specified common-mode voltage range.

  • The REF pin is used to set the output voltage reference for the INA129UA/2K5E4. It can be connected to a voltage reference or a fixed voltage source to set the output voltage range. The REF pin can also be left unconnected, in which case the output voltage range will be centered around 0V.

  • The INA129UA/2K5E4 is designed for low-frequency applications, and its bandwidth is limited to 2.5kHz. While it can be used for higher-frequency applications, the device's performance may degrade, and the output signal may be distorted. For high-frequency applications, consider using a different amplifier or a specialized high-frequency instrumentation amplifier.

  • The gain of the INA129UA/2K5E4 can be calculated using the formula: Gain = (49.4kΩ/RG) + 1, where RG is the gain resistor connected between the GAIN pin and the REF pin. The gain can be set to a value between 1 and 1000.
