Product details

Precision 2.5V reference for the analog rail

The Maxim Integrated MAX873AESA+ is a series voltage reference that delivers a fixed 2.5 V output with a tight initial tolerance of ±0.06% and a low temperature coefficient of 7 ppm/°C. It operates from a 4.5 V to 18 V input supply, drawing 600 µA quiescent current while sourcing up to 10 mA to the load.

The 8-SOIC (0.154", 3.90 mm width) package is a standard footprint shared by countless op-amps and references. The part ships in Tube form per the listing.

It is ROHS3 compliant.

Frequently asked questions

What is the difference between MAX873AESA+ and MAX873AESA?

The MAX873AESA+ is the ROHS3-compliant version of the MAX873AESA. The electrical specifications — 2.5 V output, ±0.06% tolerance, 7 ppm/°C drift, 10 mA output — are identical. The '+' suffix indicates lead-free / RoHS-compliant finish. They are pin-compatible and functionally interchangeable; the choice depends on your assembly's RoHS exemption requirements.

Is MAX873AESA+ available in tape and reel?

The listing shows the MAX873AESA+ shipping in Tube packaging. A tape-and-reel variant may exist under a different order code suffix — check the full product family or request a quote for your preferred packaging format.

Is MAX873AESA+ RoHS compliant?

Yes, the MAX873AESA+ is ROHS3 compliant.
