Output voltage adjusts from a minimum of 1.233 V up to 10 V using two external resistors, giving the designer a single BOM line to cover multiple reference voltages across a board. The shunt topology means it sinks current from the load rather than sourcing it — the external resistor sets the bias, and the 80 µA minimum cathode current keeps the reference in regulation down to light loads. ## Noise floor and temperature drift — what they mean for the signal chain Broadband noise is specified at 20 µVrms over a 10 Hz to 10 kHz bandwidth. In a 16-bit ADC system with a 4.096 V reference, that noise integrates to roughly 0.3 LSBs rms — negligible for most industrial measurements, but worth derating if the reference feeds a high-resolution delta-sigma converter running at low oversampling ratios. The 100 ppm/°C temperature coefficient means the output voltage shifts by 100 parts per million for every degree Celsius change.","metaTitle":"LM4041CIDBZT Texas Instruments Shunt Reference, ±0.5%","metaDescription":"Texas Instruments LM4041CIDBZT adjustable shunt voltage reference, ±0.5% tolerance, SOT-23-3, active production, RoHS3 compliant.
