For a 12-bit system with a 3 V reference (one LSB ≈ 0.73 mV), that drift consumes roughly 0.6 LSBs of error budget — acceptable for most industrial control loops but worth derating if the system targets 14-bit resolution.
Yes. The LM4040DEM3X-3.0/NOPB is a shunt voltage reference specifically designed for that role. It provides a fixed 3 V output with ±1% tolerance, 35 µVrms noise, and can sink up to 15 mA. It is suitable as a reference for ADCs, DACs, and comparators in industrial-temperature environments.
