24-bit, 144k SPS, four differential channels
The ADS1274IPAPR: Each of the four inputs is differential, giving you a full-scale range defined by the external reference voltage. Data is read out over an SPI-compatible serial interface, which keeps the pin count manageable on the 64-pin HTQFP package. The digital supply runs on 1.65 V to 1.95 V, while the analog section needs a clean 5 V rail.
Industrial temperature range and package fit
The external reference requirement means the ADC's accuracy is set by the reference you choose — a low-drift reference like the REF50xx series is a natural pairing. The SPI interface allows daisy-chaining multiple ADS1274s on a single bus, useful for higher channel-count systems without adding GPIOs.
