It accepts an input from 8V to 30V and delivers a regulated 5V at up to 21 mA output current — enough to bias multiple ADC reference inputs or a small analog front-end without an extra buffer. For a 10°C shift, the output moves about 3.25 mV — a factor to consider when the ADC full-scale error budget is tight. ## 12 µVp-p low-frequency noise floor A 16-bit ADC with a 5V reference sees about 76 µV per LSB; the reference's own noise consumes roughly 16% of that budget before the ADC's noise is added. For 18-bit or higher systems, external filtering or a lower-noise reference is worth evaluating. The 1.6 mA quiescent supply current is modest — the reference's own draw adds to the system power budget but stays well below the 21 mA output ceiling, so the load current dominates total consumption in most designs. ## Active lifecycle — no last-time-buy pressure ROHS3 compliance covers global regulatory requirements for lead-free assembly. The 8-SOIC package is a standard JEDEC outline — the 0.154-inch body width and 3.90 mm footprint match the industry-common SOIC-8 land pattern, so no board respin is needed when swapping between qualified suppliers. ## Sourcing and availability Tape & Reel packaging supports automated pick-and-place; Cut Tape quantities are also available for prototyping runs.","metaTitle":"REF02CSA+T Analog Devices 5V Series Reference, 8-SOIC","metaDescription":"REF02CSA+T 5V fixed output series voltage reference from Analog Devices. ±1% tolerance, 65ppm/°C drift, 12µVp-p noise.
