Precision anchor for 16-bit measurement chains
The MAX6350ESA+ is a 5V series voltage reference built around a buried-zener topology — the same architecture used in lab-grade standards. For a 16-bit ADC with a 5V reference, that noise contribution is under 0.2 LSB — you can skip the post-filter LC stage on the reference input in most designs.
Supply flexibility and drive capability
Input voltage spans 8V to 36V, so the part runs directly from a 12V or 24V industrial rail without a pre-regulator. The 15 mA output current can bias several ADC reference inputs or a precision op-amp string; the 3.3 mA quiescent supply current keeps the thermal budget tight even in a sealed enclosure. The 8-SOIC package (0.154" body width, 3.90 mm) is a standard footprint — no exotic land pattern.
Lifecycle and compliance at a glance
ROHS3 compliant, so it ships without any RoHS exemption declarations. For a BOM that needs a stable 5V reference with a 20-year production horizon, this part is a safe bet.
