The ADS1271IBPW is a 24-bit delta-sigma Analog-to-digital Converter (ADC) with a data rate up to 105kSPS. It offers unique combination of excellent DC accuracy and outstanding AC performance. The high-order, chopper-stabilized modulator achieves very low drift with low in-band noise. The on board decimation filter suppresses modulator and signal out-of-band noise. Traditionally, industrial delta-sigma ADC offering good drift performance use digital filters with large pass-band droop. As a result, it has limited signal bandwidth and is mostly suited for DC measurements. High-resolution ADC in audio applications offers larger usable bandwidths, but the offset and drift specification are significantly weaker than their industrial counterparts. The ADC combines these converters, allowing high-precision industrial measurement with excellent DC and AC specifications ensured over an extended industrial temperature range.
