FEATURES
DESCRIPTION
23
24 Bits, No Missing Codes
The
ADS1246,
ADS1247,
and
ADS1248
are
highly-integrated, precision, 24-bit analog-to-digital
Data Output Rates Up to 2kSPS
converters (ADCs). The ADS1246/7/8 feature an
Single-Cycle Settling for All Data Rates
onboard, low-noise, programmable gain amplifier
Simultaneous 50/60Hz Rejection at 20SPS
(PGA), a precision delta-sigma (
ΔΣ) ADC with a
4 Differential/7 Single-Ended Inputs (ADS1248)
single-cycle settling digital filter, and an internal
oscillator. The ADS1247 and ADS1248 also provide a
2 Differential/3 Single-Ended Inputs (ADS1247)
built-in, very low drift voltage reference with 10mA
Low-Noise PGA: 48nV at PGA = 128
output capacity, and two matched programmable
Matched Current Source DACs
current
digital-to-analog
converters
(DACs).
The
ADS1246/7/8 provide a complete front-end solution
Very Low Drift Internal Voltage Reference:
for temperature sensor applications including thermal
10ppm/°C (max)
couples, thermistors, and RTDs.
Sensor Burnout Detection
An input multiplexer supports four differential inputs
4/8 General-Purpose I/Os (ADS1247/8)
for the ADS1248, two for the ADS1247, and one for
Internal Temperature Sensor
the ADS1246. In addition, the multiplexer has a
sensor
burnout
detect,
voltage
bias
for
Power Supply and VREF Monitoring
thermocouples,
system
monitoring,
and
(ADS1247/8)
general-purpose
digital
I/Os
(ADS1247
and
Self and System Calibration
ADS1248). The onboard, low-noise PGA provides
SPI™-Compatible Serial Interface
selectable gains of 1 to 128. The
ΔΣ modulator and
adjustable digital filter settle in only one cycle, for fast
Analog Supply Unipolar (+2.7V to
channel cycling when using the input multiplexer, and
+5.25V)/Bipolar (±2.5V) Operation
support data rates up to 2kSPS. For data rates of
Digital Supply: +2.7V to +5.25V
20SPS or less, both 50Hz and 60Hz interference are
Operating Temperature –40°C to +125°C
rejected by the filter.
The ADS1246 is offered in a small TSSOP-16
APPLICATIONS
package, the ADS1247 is available in a TSSOP-20
Temperature Measurement
package, and the ADS1248 in a TSSOP-28 package.
RTDs, Thermocouples, and Thermistors
All three devices are rated over the extended
specified temperature range of –40°C to +105°C.
