For a 12-bit ADC with a 1.8V reference, that noise contributes about 0.3 LSB peak-to-peak at the converter's full scale; clean enough for most industrial measurements. ## Supply budget and output drive Quiescent supply current is 100 µA typical, and it can source up to 20 mA to the load. That 20 mA is enough to bias a string of pull-ups or feed the reference input of a handful of ADCs without an external buffer.","metaTitle":"Texas Instruments LM4128DMF-1.8/NOPB Series Voltage","metaDescription":"Texas Instruments LM4128DMF-1.8/NOPB series voltage reference, fixed 1.8V output, ±1% tolerance, SOT-23-5 package.
