What this reference does on your board
The MAX6126AASA41+T is a series voltage reference with a fixed 4.096 V output and ±0.02% tolerance. Temperature coefficient is 5 ppm/°C over -40°C to 125°C.
Supply and load conditions
Input voltage range is 4.3 V to 12.6 V. Supply current is 725 µA; output current is 10 mA. Packaged in an 8-SOIC (3.90 mm width), surface-mount. No heatsinking required at 10 mA output; the SOIC footprint handles the dissipation.
Lifecycle and sourcing position
No end-of-life notice or last-time-buy schedule is in effect. For BOM planning, this part is a low-risk line item — no imminent obsolescence to trigger a qualification cycle.
