The is a multichannel Analog-to-Digital Converter ADC with simultaneous sampling, 24-bit, delta-sigma ΔΣ, a built-in programmable gain amplifier PGA, internal reference and an onboard oscillator. The device 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 device enables the creation of scalable industrial power systems at significantly reduced power. The device has a flexible input multiplexer per channel that can be independently connected to the internally-generated signals for test, temperature and fault detection. Fault detection can be implemented internal to the device, using the integrated comparators with digital-to-analog converter DAC-controlled trigger levels. The device can operate at data rates as high as 64kSPS.
