ADS1174IPAPRG4

四/八通道，同步采样， 16位模拟至数字转换器 Quad/Octal, Simultaneous Sampling, 16-Bit Analog-to-Digital Converters

DESCRIPON

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.
