The ADS1255 and ADS1256 are extremely low-noise, 24-bit analog-to-digital (A/D) converters. They provide complete high-resolution measurement solutions for the most demanding applications. The converter is comprised of a 4th-order, delta-sigma (∆Σ) modulator followed by a programmable digital filter. A flexible input multiplexer handles differential or single-ended signals and includes circuitry to verify the integrity of the external sensor connected to the inputs. The selectable input buffer greatly increases the converter's input impedance, reducing power supply noise and common-mode noise. The ADS1256 also includes an optional low-noise gain amplifier (PGA) that increases the signal range, reduces noise, and further improves the converter's dynamic range.
