The new ADS1271 is a 24-bit, 105kSPS delta-sigma ADC that provides a breakthrough combination of excellent DC accuracy and outstanding AC performance, enabling a new level of precision measurements in industrial, medical and automotive applications.

Traditionally, industrial delta-sigma ADCs offering od drift performance used digital filters with large passband droop, resulting in limited signal bandwidth mostly suited for DC measurements. High-resolution ADCs for audio applications offer larger usable bandwidths, but the offset and drift are significantly worse (and often unspecified) than their industrial counterparts. The ADS1271 combines these two converter types, allowing high-precision measurements with excellent DC and AC specifications ensured over a -40C to +105C temperature range.
