This is the noise that lands in the same passband as a precision weigh-scale or thermocouple measurement. At 3 µVp-p, the reference contributes about 0.4 LSB of peak-to-peak noise to a 16-bit system — the converter's own noise will dominate, not the reference. ## Input range and output current — sizing the supply rail The REF5050IDRG4 requires an input voltage between 5.2 V and 18 V. The 10 mA output current rating is enough to bias a handful of ADC reference inputs or a small resistive divider, but not enough to power downstream active circuitry — plan a separate LDO for the analog supply rail. The quiescent current is 1.2 mA, which matters for loop-powered 4-20 mA transmitters where every milliamp is budgeted.
