The ADS117L14 (quad) and ADS117L18 (octal) are 16-bit, delta-sigma (ΔΣ), analog-to-digital converters (ADCs). 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). The 24-bit ADS127L14 (quad) and ADS127L18 (octal) ADCs are pin-compatible devices for increased resolution.
