ADS131E08SPAGR

The ADS131E08S is a multichannel, simultaneous
sampling, 24-bit, delta-sigma (ΔΣ), analog-to-digital
converter (ADC) 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 3 ms 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 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.
The ADS131E08S has an individual 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
ADS131E08S can operate at data rates as high as
64 kSPS.
The complete analog front-end (AFE) solution is
available in a 64-pin TQFP package and is specified
over the industrial temperature range of –40°C to
+105°C.
