3 Description
The ADS131E0x are a family of multichannel,
simultaneous sampling, 24-bit, delta-sigma (ΔΣ),
analog-to-digital converters (ADCs) with a built-in
programmable gain amplifier (PGA), internal
reference, and an onboard oscillator. The ADC wide
dynamic range, scalable data rates, and internal fault
detect monitors make the ADS131E0x attractive in
industrial power monitoring and protection as well as
test and measurement applications. True highimpedance
inputs enable the ADS131E0x to directly
interface with a resistor-divider network or a voltage
transformer to measure line voltage, or a current
transformer or Rogowski coil to measure line 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.
These complete analog front-end (AFE) solutions are
packaged in a TQFP-64 package and are specified
over the industrial temperature range of –40°C to
+105°C.
