Product details

2.048V series reference with ±0.2% initial accuracy

The MAX6018AEUR21 is a precision series voltage reference from Maxim Integrated, delivering a fixed 2.048V output with ±0.2% initial tolerance — tight enough to set the full-scale range of a 12-bit ADC without external trimming, provided the reference input of the converter can accept the 2.048V level. Operating from a 2.25V to 5.5V input rail, it sources up to 1 mA output current while drawing only 6 µA quiescent supply current — a combination that suits battery-powered instrumentation where every microamp of overhead matters for the sleep-mode budget.

SOT-23-3 package and board integration

Housed in the SOT-23-3 package (TO-236-3 / SC-59 equivalent), the MAX6018AEUR21 occupies a standard three-lead footprint with 0.95 mm pitch — the same land pattern used by countless shunt and series references, so no PCB layout change is needed when swapping between compatible SOT-23 references.

Frequently asked questions

What package does the MAX6018AEUR21 use?

The MAX6018AEUR21 is supplied in a SOT-23-3 surface-mount package (also listed as TO-236-3 or SC-59). The three-lead footprint with 0.95 mm pitch is a standard layout shared by many series and shunt references.

Is the MAX6018AEUR21 RoHS compliant?

Verify the material composition with the manufacturer if your assembly process requires RoHS exemption documentation or a fully lead-free bill of materials.
