TIPD188, High-Resolution, Low-Drift, Precision Weigh-Scale Reference Design with AC Bridge Excitation

TIPD188, High-Resolution, Low-Drift, Precision Weigh-Scale Reference Design with AC Bridge Excitation. This precision weigh-scale reference design achieves greater than 50,000 noise-free counts of resolution. Offset and offset drift errors are nearly eliminated by ac bridge excitation. This design takes advantage of the high-resolution ADS1262 delta-sigma ADC
