The DADS131E04/08 is a series of multi-channel, synchronous sampling, 24-bit delta - sigma analog-to-digital converters (ADCs) with a built-in programmable gain amplifier (PGA), internal reference, and onboard oscillator. With its wide dynamic range, scalable data transfer rates, and internal fault detection monitor, the DADS131E04/08 is favored for industrial power monitoring and protection, as well as test and measurement applications. True high-impedance inputs allow the DADS131E04/08 to be directly connected to a resistive divider network or voltage transformer to measure line voltage, or connected to a current transformer or Rogowski coil to measure current. 

The DADS131E04/08 features a flexible input multiplexer on each channel, which is independently connected to internally generated signals for test, temperature, and fault detection. Fault detection is performed internally by the device, which uses an integrated comparator with a trigger level controlled by a digital-to-analog converter (DAC). The DADS131E04/08 can operate at data rates up to 64 kSPS.

These complete analog front-end (AFE) solutions are packaged in a TQFP-64 package and rated for industrial
