Texas Instruments REF2041
The REF20xx provides a reference voltage (VREF) for the ADC and a second highly-accurate voltage (VBIAS) that can be used to bias the input bipolar signals. The REF20xx offers excellent temperature drift (8 ppm/°C, maximum) and initial accuracy (0.05%) on both the VREF and VBIAS outputs while operating at a quiescent current less than 430 µA.| Part No. | REF2041 |
