Voltage Reference Procurement Notes

Verify the specific suffix 'X' indicates tape-and-reel packaging configuration. Confirm that the 'A' grade designation corresponds to the required ±0.1% initial accuracy specification. Ensure the component meets the extended temperature range requirements (-40°C to +125°C) for your intended operating environment before finalizing procurement.

Voltage Reference Selection Notes

Select this component when high precision and low power consumption are critical in a small footprint. The A-grade variant offers superior initial accuracy compared to B or C grades. Consider the minimum operating current requirements of your circuit to ensure stability, as the device requires a minimum cathode current to maintain regulation within specified limits.
