For a 12-bit system with a 4.096 V reference (1 mV per LSB), that drift consumes about 4 LSBs of error budget — worth derating if the design sees wide thermal swings. ## Shunt topology — low quiescent overhead As a shunt reference, the TL4050B41QDBZT regulates by sinking current through the cathode. The minimum cathode current is 78 µA, so the series resistor from the supply rail must deliver at least that much plus the load current to keep the output in regulation. Maximum output current is 15 mA — the shunt can source that much to the load, but the total current through the device (load + quiescent) must stay within the power dissipation limit of the SOT-23-3 package. For a 4.096 V output, that is roughly 23 ppm rms — low enough that the reference noise does not dominate the ADC SNR in most precision measurement chains. ## Package and lifecycle The footprint is shared across many shunt references, so a PCB layout for this part accepts drop-in alternatives from the same family.","metaTitle":"TL4050B41QDBZT shunt reference, 4.096V ±0.2%, SOT-23-3","metaDescription":"Texas Instruments TL4050B41QDBZT precision shunt voltage reference, 4.096V fixed output, ±0.2% tolerance, 50ppm/°C drift.
