Voltage Reference FAQ

Can the LT6654 operate as a negative voltage reference?

Yes, by connecting the output to ground and applying a positive bias voltage to the VIN pin through a current-limiting resistor, the device can function as a negative voltage reference.

What are the bypass capacitor requirements for stable operation?

An input bypass capacitor of 0.1µF or larger is recommended, and an output capacitor of at least 1µF is required for stability.
