Description

The ADS131A02 and ADS131A04 devices are two- and four-channel, simultaneous-sampling,24-bit, delta-sigma (ΔΣ), analog-to-digital converters (ADCs). The wide dynamic range, withscalable data rates up to 128 kSPS, and internal fault monitors make the ADS131A02 or ADS131A04 agood choice when designing for energy monitoring, grid protection, and control applications. TheADC inputs can be independently and directly interfaced to a resistor-divider network, a currenttransformer, or a Rogowski coil to measure voltage or current. Flexible power-supply options,including an internal negative charge pump, are available to maximize the effective resolution forhigh dynamic range applications.

Asynchronous and synchronous master and slave interface options are available, providingADC configuration flexibility when chaining multiple devices in a single system. Several interfacechecks, ADC startup checks, and data integrity checks can be enabled on the interface to reporterrors in the ADC and during data transfer.

The complete analog front-end (AFE) solutions are packaged in a 32-pin TQFP package andare specified over the industrial temperature range of –40°C to +125°C.
