The 15 mA output current ceiling and 110 µA minimum cathode current define the resistor sizing: pick the bias resistor so the total current (load + 110 µA) stays between those limits across the supply range. ## Noise and drift — the limits that matter for precision Output noise is specified at 180 µVrms over the 10 Hz to 10 kHz bandwidth — about 18 ppm of the 10V output. That is adequate for a 12-bit ADC reference (1 LSB at 10V is 2.44 mV), but a 16-bit system would see the noise floor at roughly 3 LSBs. The temperature coefficient is 150 ppm/°C, which translates to a 1.5 mV shift over a 10°C change. For a design that holds calibration across a 50°C swing, budget for a 7.5 mV drift — check if your system's reference input tolerance accommodates that. ## Package and mounting — SOT-23-3 footprint The base product number is LM4040, which spans multiple voltage options and tolerance grades in the same SOT-23-3 footprint.","metaTitle":"Texas Instruments LM4040DIM3-10.0/NOPB Shunt Voltage","metaDescription":"Precision 10V shunt voltage reference in SOT-23-3, ±1% tolerance, 15 mA output, -40°C to 85°C.
