Texas Instruments ADS131E08S Analog Front-End for Power Monitoring

Texas Instruments ADS131E08S Analog Front-End for Power Monitoring is a multichannel, simultaneous sampling, 24-bit, delta-sigma (ΔΣ), Analog-to-Digital Converter (ADC). This device comes with built-in programmable gain amplifiers (PGAs), an internal reference, and an internal oscillator. The ADC wide dynamic range, scalable data rates, and internal fault detect monitors make the ADS131E08S very attractive in industrial power monitoring, control, and protection applications. Fast power-up time allows data to be available within 3ms of power being applied to the device for line-powered power applications. True high-impedance inputs enable the ADS131E08S to directly interface with a resistor-divider network or a voltage transformer. This can be used to measure line voltage, or a current transformer or Rogowski coil to measure line current. With high integration levels and exceptional performance, the ADS131E08S enables the creation of scalable industrial power systems at a significantly reduced size, power, and overall cost.
