ADS1174IPAPR Datasheet PDF - TI

●DESCRIPTION

●The ADS1174 (quad) and ADS1178 (octal) are multiple delta-sigma (ΔΣ) analog-to-digital converters (ADCs) with data rates up to 52k samples-per-second (SPS), which allow synchronous sampling of four and eight channels. These devices use identical packages, and are also compatible with the

●high-performance 24-bit ADS1274 and ADS1278, permitting drop-in upgrades.
