Overview
The ADS1271 is a 24-bit, delta-sigma analog-to-digital converter (ADC) with a data rate up to 105kSPS. 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 0.005dB of ripple. Traditionally, industrial delta-sigma ADCs offering good drift performance use digital filters with large passband 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. The ADS1271 combines these converters, allowing high-precision industrial measurement with excellent DC and AC specifications ensured over an extended industrial temperature range. Three operating modes allow for optimization of speed, resolution, and power. A selectable SPI or a frame-sync serial interface provides for convenient interfacing to microcontrollers or DSPs. The output from the modulator is accessible for external digital filter applications. All operations, including internal offset calibration, are controlled directly by pins; there are no registers to program.
