Overview: Product Folder Order Now Technical Documents Tools & Software Support & Community Reference Design REF1925, REF1930, REF1933, REF1941 SBOS697A – SEPTEMBER 2014 – REVISED JANUARY 2017 REF19xx Low-Drift, Low-Power,.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

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 can be used to bias the input bipolar signals.

The REF19xx offers excellent temperature drift (25 ppm/°C, max) and initial accuracy (0.1%) on both the VREF and VBIAS outputs while operating at a quiescent current less than 430 µA.
