Voltage Reference Procurement Notes

Verify the specific grade suffix 'BI' corresponds to the required 0.1% accuracy and 20ppm/°C drift specifications. Confirm the DC package designation matches the intended PCB footprint. Ensure the #TRMPBF suffix aligns with the required tape and reel packaging format for automated assembly processes.

Voltage Reference Selection Notes

Select this component when a 4.096V reference with B-grade accuracy is required. Consider the DFN package dimensions for space-constrained designs. Evaluate the 20ppm/°C temperature coefficient against system stability requirements. Verify that the 5mA output drive meets the load demands of the connected circuitry.

Voltage Reference Part Context

This part belongs to the LT6656 family of 1µA precision series voltage references. It shares core architectural features with other variants but differs in output voltage, accuracy grade, and package type. The BIDC variant specifically combines the industrial temperature range, B-grade performance, and DFN packaging.
