How to use

Place the reference IC close to the analog converter or sensor input to minimize trace length between the reference output and the reference input pins of the target device. Follow the manufacturer’s recommended decoupling practices by adding a suitable bypass capacitor on the reference output to stabilize transient response where indicated. Ensure correct orientation and soldering for the SOT-23 package and verify that supply voltage and ambient conditions are within the device’s specified operating range before applying the reference to precision circuits.

Рекомендации по использованию

For stable measurement performance, avoid routing noisy digital lines near the reference output and use a single-point ground return for the reference and analog sections. Where long-term stability is critical, allow a brief warm-up period after power-up and verify the reference voltage under actual operating conditions.
