DescriptionThe ADS1246, ADS1247, and ADS1248 devices are
precision, 24-bit analog-to-digital converters (ADCs)
that include many integrated features to reduce
system cost and component count for sensor
measurement applications. The devices featurea
low-noise, programmable gain amplifier (PGA),a
precision delta-sigma (ΔΣ) ADC witha single-cycle
settling digital filter, and an internal oscillator. The
ADS1247 and ADS1248 devices also providea built-
in, low-drift voltage reference, and two matched
programmable excitation current sources (IDACs). input multiplexer supports four differential inputs
for the ADS1248, two for the ADS1247, and one for
the ADS1246.In addition, the multiplexer integrates
sensor burn-out detection, voltage bias for
thermocouples, system monitoring, and general
purpose digital I/Os (ADS1247 and ADS1248). The
PGA provides selectable gains upto 128 V/V. These
features providea complete front-end solution for
temperature sensor measurement applications
including thermocouples, thermistors, and resistance
temperature detectors (RTDs) and other small signal
measurements including resistive bridge sensors.
The digital filter settlesina single cycleto support
fast channel cycling when using the input multiplexer
and provides data ratesupto2 kSPS. For data rates20 SPSor less, both 50-Hz and 60-Hz interference
are rejectedby the filter.
