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.
