ADS131A02IPBSR-24-Bit, 128kSPS, 2-Ch, Simultaneous Sampling, Delta-Sigma ADC

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, with scalable data rates up to 128 kSPS, and internal fault monitors make the ADS131A02 or ADS131A04 a good choice when designing for energy monitoring, grid protection, and control applications. The ADC inputs can be independently and directly interfaced to a resistor-divider network, a current transformer, 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 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 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.
