Description

The ADS127L14 (quad) and ADS127L18 (octal) are 24-bit, delta-sigma (ΔΣ), analog-to-digital converters (ADCs) based on the single-channel ADS127L11. The devices provide simultaneous sampling of four or eight channels with data rates up to 512kSPS (wideband filter mode) and 1365kSPS (low-latency filter mode).
