Precision 5V series reference in SOT-23-6
The MAX6033AAUT50: Operating from a 5.2V to 12.6V input rail, it supplies up to 15 mA to the load while drawing only 85 µA quiescent current — the low self-heating keeps the output stable even when the load current varies.
Noise floor and drift — what they mean for the ADC chain
For a 16-bit converter with a 5V reference, 26 µVrms represents roughly 0.3 LSB of noise, leaving headroom for the converter's own noise contribution. The 10ppm/°C drift means the output shifts by 50 µV per °C at 5V. In an industrial sensor module that sees a 50°C swing on the PCB, the reference drifts by 2.5 mV — a factor to budget into the system accuracy calculation.
Note the RoHS compliance status: this part is listed as RoHS non-compliant. If your assembly requires RoHS exemption or lead-free processing, verify the solder profile compatibility with the SOT-23-6 package before committing the BOM line.
