XTR116U Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the XTR116U?
  The recommended power-up sequence is to apply VCC first, followed by VREF, and then the input signal. This ensures proper internal biasing and prevents latch-up.
• How do I ensure accurate voltage measurement with the XTR116U?
  To ensure accurate voltage measurement, use a low-impedance voltage source, keep the input leads short, and avoid noise coupling. Also, consider using a voltage reference with low temperature coefficient and low noise.
• What is the maximum input voltage that the XTR116U can handle?
  The XTR116U can handle input voltages up to 36V, but it's recommended to limit the input voltage to 30V or less to ensure reliable operation and prevent damage.
• Can I use the XTR116U with a single supply voltage?
  Yes, the XTR116U can operate with a single supply voltage, but it's essential to ensure the input signal is within the common-mode range (VCC - 2V to VCC + 0.5V) to maintain accuracy.
• How do I minimize noise and interference when using the XTR116U?
  To minimize noise and interference, use a ground plane, keep the input leads short, and use shielding or twisted pairs for the input signal. Also, consider using a low-pass filter or a ferrite bead to reduce high-frequency noise.
