FEATURES
DESCRIPTION
The ADS1246, ADS1247, and ADS1248 are
23
• 24 Bits, No Missing Codes
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
(PGA), a precision delta-sigma (ΔΣ) ADC with a
• Simultaneous 50/60Hz Rejection at 20SPS
single-cycle settling digital filter, and an internal
• 4 Differential/7 Single-Ended Inputs (ADS1248)
oscillator. The ADS1247 and ADS1248 also provide a
• 2 Differential/3 Single-Ended Inputs (ADS1247)
built-in, very low drift voltage reference with 10mA
output capacity, and two matched programmable
• Low-Noise PGA: 48nV at PGA = 128
current digital-to-analog converters (DACs). The
• Matched Current Source DACs
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
the ADS1246. In addition, the multiplexer has a
• Internal Temperature Sensor

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
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
rejected by the filter.
• Operating Temperature –40°C to +125°C
The ADS1246 is offered in a small TSSOP-16
APPLICATIONS
package, the ADS1247 is available in a TSSOP-20
package, and the ADS1248 in a TSSOP-28 package.
• Temperature Measurement
All three devices are rated over the extended
– RTDs, Thermocouples, and Thermistors
specified temperature range of –40°C to +105°C.
• Pressure Measurement
• Industrial Process Control
