Documents With a 15 V-excited load cell output centered around 7.5 V common-mode, how is it typically interfaced to an ADC like AD7191?

With a 15 V-excited load cell output centered around 7.5 V common-mode, how is it typically interfaced to an ADC like AD7191?

A precision in-amp with wide common-mode range—like the AD8420 or AD8421—works best for this.
