The ADS131A02 and ADS131A04 are two- and fourchannel, simultaneously-sampling, 24-bit, delta-sigma (ΔΣ), analog-to-digital converters (ADCs). The wide dynamic range, scalable data rates, and internal fault monitors make the ADS131A02 and ADS131A04 ideally-suited for energy monitoring, protection, and control applications. The ADC inputs can be independently and directly interfaced to a resistordivider network, a transformer to measure voltage or current, or a Rogowski coil to measure current. Flexible power-supply options, including an internal negative charge pump, are available to maximize the effective resolution for high dynamic range applications. Asynchronous and synchronous master and slave interface options are available, providing ADC configuration flexibility when chaining multiple devices in a single system. Several interface checks, ADC startup checks, and data integrity checks can be enabled on the interface to report errors in the ADC and during data transfer. The ADS131A02 and ADS131A04 support data rates up to 128 kSPS. The complete analog front-end (AFE) solutions are packaged in a 32-pin TQFP package and are specified over the industrial temperature range of –40°C to +125°C.
