General Description

The ADS131A02 and ADS131A04 devices are twoand 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 resistordivider network, a current transformer, or a Rogowski coil to measure voltage or current.
