Texas Instruments ADS131E04 / ADS131E06 / ADS131E08 Analog Front-End for Power Monitoring
Texas Instruments ADS131E04 / ADS131E06 / ADS131E08 Analog Front-End devices for Power Monitoring, Control, and Protection are part of a family of multichannel, simultaneous sampling, 24- and 16-bit, delta-sigma (ΔΣ) analog-to-digital converters (ADCs) with a built-in programmable gain amplifier (PGA), internal reference, and an onboard oscillator. TI ADS131E0x AFE devices incorporate features commonly required in industrial power monitoring, control, and protection applications. The ADS131E0x inputs can be independently and directly interfaced with a resistor-divider network or a transformer to measure voltage. The inputs can also be interfaced to a current transformer or Rogowski coil to measure current. With high integration levels and exceptional performance, the ADS131E0x family enables the creation of scalable industrial power systems at significantly reduced size, power, and low overall cost. The ADS131E0x AFE devices have a flexible input multiplexer per channel that can be independently connected to the internally-generated signals for test, temperature, and fault detection. These TI ADCs can operate at data rates as high as 64kSPS.
