5V fixed reference — 12ppm/°C drift, 2.85µVp-p noise
The MAX6126B50: This combination makes it suitable for precision ADC/DAC reference applications where the drift across temperature directly sets the system accuracy floor. Low-frequency noise is specified at 2.85µVp-p from 0.1Hz to 10Hz — this is the band where flicker noise dominates, and for a 16-bit ADC with a 5V reference, this noise contribution stays below 1 LSB at the converter's noise floor.
Supply and load range — 5.2V to 12.6V input, 10mA output
Input voltage range spans 5.2V to 12.6V, with a 725µA quiescent supply current. The 10mA output current capability allows the reference to drive multiple ADC reference inputs or a small resistive divider without an external buffer. For a precision reference in an engine bay or outdoor base station, the 125°C rating means the drift spec holds across the hottest operating condition without derating.
Package and board-fit — 8-MSOP, surface mount
Available in an 8-lead TSSOP/MSOP package (3.00mm width), with the supplier device package listed as 8-uMAX/uSOP. The 0.118-inch body width fits standard 8-pin MSOP footprints, and the surface-mount profile suits automated assembly lines. The series reference topology means the output is internally compensated — no external capacitor is required for stability, though a 0.1µF bypass at the input is standard practice for supply decoupling.
Active lifecycle — RoHS non-compliant
The part is marked RoHS non-compliant — verify your assembly's exemption status or plan for a lead-free alternative if the BOM requires full RoHS compliance.
