ADS1271IPWG4

АЦП, 24 бит, 105 Квыборок/с, Однополярный, 4.75 В, 5.25 В, TSSOP.

The ADS1271IPWG4 is a 24-bit Analogue-to-digital Converter with a data rate up to 105kSPS. It offers an 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 onboard decimation filter suppresses modulator and signal out-of-band noise. The ADS1271 ADC provides an usable signal bandwidth up to 90% of the Nyquist rate with less than 0.005dB of ripple. Traditionally, industrial delta-sigma ADC offers good drift performance use digital filters with large pass-band droop. As a result, they have limited signal bandwidth and are mostly suited for DC measurements. High-resolution ADCs in audio applications offer larger usable bandwidths, but the offset and drift specification are significantly weaker than their industrial counterparts. Three operating modes allow for optimization of speed, resolution and power.
