24-Bit Analog-to-Digital Converters for Temperature Sensors

FEATURES

DESCRIPTION

•

24 Bits, No Missing Codes

The ADS1246, ADS1247, and ADS1248 are

highly-integrated, precision, 24-bit analog-to-digital

converters (ADCs). The ADS1246/7/8 feature an

onboard, low-noise, programmable gain amplifier

•

Data Output Rates Up to 2kSPS

Single-Cycle Settling for All Data Rates

Simultaneous 50/60Hz Rejection at 20SPS

4 Differential/7 Single-Ended Inputs (ADS1248)

2 Differential/3 Single-Ended Inputs (ADS1247)

Low-Noise PGA: 48nV at PGA = 128

Matched Current Source DACs

(PGA),

precision delta-sigma ADC with

single-cycle settling digital filter, and an internal

oscillator. The ADS1247 and ADS1248 also provide a

built-in, very low drift voltage reference with 10mA

output capacity, and two matched programmable

current digital-to-analog converters (DACs). The

ADS1246/7/8 provide a complete front-end solution

for temperature/bridge sensor applications including

thermal couples, thermistors, RTDs, and strain-gauge

applications.

Very Low Drift Internal Voltage Reference:

10ppm/°C (max)

•

Sensor Burnout Detection

4/8 General-Purpose I/Os (ADS1247/48)

Internal Temperature Sensor

An input multiplexer supports four differential inputs

for the ADS1248, two for the ADS1247, and one for

the ADS1246. In addition, the multiplexer has a

for

•

Self and System Calibration

general-purpose digital I/Os

(ADS1247 and

SPI™-Compatible Serial Interface

ADS1248). The onboard, low-noise PGA provides

selectable gains of 1 to 128. The delta-sigma

modulator and adjustable digital filter settle in only

one cycle, for fast channel cycling when using the

input multiplexer, and support data rates up to

2kSPS. For data rates of 20SPS or less, both 50Hz

and 60Hz interference are rejected by the filter.

Analog Supply Unipolar (+2.7V to

+5.25V)/Bipolar (±2.5V) Operation

•

Digital Supply: +2.7V to +5.25V

Operating Temperature –40°C to +125°C

APPLICATIONS

•

The ADS1246 is offered in a small TSSOP-16

package, the ADS1247 is available in a TSSOP-20

package, and the ADS1248 in a TSSOP-28 package.

All three devices are rated over the extended

specified temperature range of –40°C to +105°C.
