Initial tolerance is ±0.2 %, which holds the reference uncertainty to 2.5 mV at the 1.233 V minimum output — tight enough for a 12-bit ADC's 1 LSB budget without a software calibration step. The shunt topology sinks 80 µA minimum cathode current and delivers up to 12 mA to the load, so the designer sizes the bias resistor for the sum of load current plus cathode current across the full supply range. ## Temperature drift and noise floor Temperature coefficient is 100 ppm/°C typical. Wideband noise from 10 Hz to 10 kHz is 20 µVrms. That is low enough that the reference noise does not dominate the ADC's SNR for a 12-bit converter at 1.233 V (LSB ≈ 300 µV); for a 16-bit system the noise contribution should be budgeted against the converter's own noise floor. ## Package and sourcing posture Supplied in a three-pin SOT-23-3 package (also listed as TO-236-3 / SC-59 / SOT-23-3), surface-mount assembly.","metaTitle":"LM4041BIDBZT Shunt Voltage Reference, ±0.2%, 1.233V to 10V","metaDescription":"Precision adjustable shunt reference by Texas Instruments, ±0.2% tolerance, 12 mA output, 100 ppm/°C drift.
