Product details

Precision voltage reference for ADC and sensor front-ends

The MAX6126AASA25+T is a series voltage reference from Analog Devices that delivers a fixed 2.5V output with ±0.02% initial tolerance — this sets the absolute accuracy floor for any measurement chain that references it.

Supply and load considerations for BOM integration

Output current capability is 10 mA — enough to drive the reference input of a single SAR ADC or a small resistive divider, but not intended to power external loads beyond that limit. Quiescent supply current is 725 µA typical, which is the overhead the reference draws from the input rail regardless of load — budget this into the system power calculation, especially in battery-powered designs.

Package, mounting, and production status

Supplier device package is listed as 8-SOIC, matching the package / case field — no exposed pad or thermal slug to design for. CT is available for prototyping or low-volume builds.

Frequently asked questions

What is the temperature coefficient of MAX6126AASA25+T?

The temperature coefficient is 5 ppm/°C, which is the maximum drift rate over the -40°C to +125°C operating temperature range. For a 2.5V output, this equates to a worst-case shift of 12.5 µV per degree Celsius.

What is the supply current of MAX6126AASA25+T?

The typical supply current is 725 µA, drawn from the input voltage rail (2.7V to 12.6V) to power the internal reference circuitry. This is the quiescent current and does not include the output load current.

Does MAX6126AASA25+T come in tape and reel?

Yes, the MAX6126AASA25+T is available in Tape & Reel (TR) packaging, as indicated by the +T suffix in the order code. It is also offered in Cut Tape (CT) for smaller quantities.
