The ADS1271 is a 24-bit, delta-sigma analog-to-digital converter (ADC) with a data rate up to 105 kSPS. It offers a 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 provides a usable signal bandwidth up to 90% of the Nyquist rate with less than 0.005 dB of ripple. Traditionally, industrial delta-sigma ADCs offering good drift performance use digital filters with linear phase response and low out-of-band noise. The ADS1271 employs a novel digital filter design that offers the same out-of-band rejection as linear phase filters, but with significantly lower in-band noise. This new digital filter design also offers low power consumption and high integration, making it an ideal choice for multichannel applications.
