Texas Instruments ADS1278
the ADS1274 (quad) and ADS1278 (octal) are 24-bit, delta-sigma (ΔΣ) analog-to-digital converters (ADCs) with data rates up to 144k samples per second (SPS), allowing simultaneous sampling of four or eight channels. The devices are offered in identical packages, permitting drop-in expandability.| Part No. | ADS1278 |

DESCRIPTION
Based on the single-channel ADS1271, 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.
