ADS1278-EP Overview
Description
Based on the single-channel ADS1271, the ADS1278 (octal) is a 24-bit, delta-sigma (ΔΣ) analog-to-digital converter (ADC) with data rates up to 128 k samples per second (SPS), allowing simultaneous sampling of eight channels. Traditionally, industrial delta-sigma ADCs offering good drift performance use digital filters with large passband droop.
