Product Summary

The ADS1271IPWR is a 24-bit, delta-sigma analog-to-digital converter (ADC) with a data rate up to 105kSPS. The ADS1271IPWR 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 ADS1271IPWR provides a usable signal bandwidth up to 90% of the Nyquist rate with less than 0.005dB of ripple. The applications of the ADS1271IPWR include Vibration/Modal Analysis, Acoustics, Dynamic Strain Gauges, Pressure Sensors and Test and Measurement.
