SBAS561 –JUNE 2012  
Analog Front-End for Power Monitoring, Control, and Protection  
Check for Samples: ADS131E04, ADS131E06 , ADS131E08  
The ADS131E0x 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 have 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 ADS131E0x can operate  
at data rates as high as 64 kSPS.
