REF1941, REF1925, Voltage References

Applications with only a positive supply voltage often require an additional stable voltage in the middle of the analog-to-digital converter (ADC) input range to bias input bipolar signals.

The REF19xx provides a reference voltage (VREF) for the ADC and a second highly-accurate voltage (VBIAS) that
