Product Summary
The ADS1255IDBT is a extremely low-noise, 24-bit analog-to-digital (A/D) converter. The ADS1255IDBT provides complete high-resolution measurement solutions for the most demanding applications. The converter is comprised of a 4th-order, delta-sigma (ΔΣ) 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 applications of the ADS1255IDBT include Weigh Scales, Scientific Instrumentation, Industrial Process Control, Medical Equipment, Test and Measurement.
