24 Bit Analog to Digital Converter 4, 8 Input 4 Sigma-Delta 56-VQFN (7x7)
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).
