ADS131E08IPAG Description

The ADS131E08IPAG is a family of multichannel, simultaneous sampling, 24-bit, delta-sigma (ΔΣ), analog-to-digital converters (ADCs) with a built-in programmable gain amplifier (PGA), internal reference, and an onboard oscillator. The ADC's wide dynamic range, scalable data rates, and internal fault detection monitors make the ADS131E08IPAG attractive in industrial power monitoring and protection as well as test and measurement applications. True high impedance inputs enable the ADS131E08IPAG to directly interface with a resistor-divider network or a voltage transformer to measure line voltage, or a current transformer or Rogowski coil to measure line current.
