What this reference does on the board
The MAX6018BEUR16+T is a series voltage reference from Analog Devices that delivers a fixed 1.6 V output with ±0.4% initial tolerance. It runs from an input rail as low as 1.8 V up to 5.5 V, drawing only 6 µA of supply current — a combination that makes it a natural fit for battery-powered sensor nodes, portable instrumentation, and low-dropout ADC reference rails where every microamp of overhead matters. The SOT-23-3 package keeps the footprint small enough for space-constrained designs, and the -40°C to 85°C industrial temperature range covers most embedded and outdoor gear without needing an automotive-grade part.
Sourcing and lifecycle
No end-of-life notice or last-time-buy window is on record. If you are stocking a spare for a production board or qualifying a second source, the active status means no LTB risk for the foreseeable future.
