Texas Instruments : A-D converters suit temperature measurement

Texas Instruments has announced a family of 24-bit, low-noise temperature measurement analog-to-digital converters (ADCs) featuring industry leading power consumption and integration. The ADS1248 and ADS1247 integrate dual matched current digital-to-analog converters (DACs), low drift internal reference, oscillator, temperature sensor, burnout detection and eight general purpose I/Os. With a data rate of 2 kSPS and only 2.56 mW of power dissipation, the ADCs provide an easy-to-use, low-power front-end solution for temperature measurement (RTDs, thermocouples, thermistors), flow/pressure measurement and industrial process control.For more product information, see:

Key Features

·       24-bit resolution, 2 kSPS data rate, 2.56 mW power dissipation
·       4 differential / 7 single-ended inputs (ADS1248); 2 differential / 3 single-ended inputs (ADS1247)
·       50/60 Hz simultaneous rejection mode
·       Low-noise programmable gain amplifier (40 nV at G=128)

Key Benefits

·       Complete precision temperature measurement ADC solution reduces device count and simplifies design without compromising performance
·       Flexible front end for wide range of industrial sensors that require high resolution and low noise
·       Excellent measurement repeatability over the -40 to +125C operating temperature range
·       Compatible devices complete the signal chain, including OPA277 and OPA333 precision operational amplifiers and REF5025 precision voltage reference

Availability and pricing

The ADS1248 and ADS1247 are available now in a TSSOP-20 package. The ADS1248 is priced at $4.95 and the ADS1247 is priced at $4.45. All pricing is in quantities of 1,000 units. For applications requiring a smaller package and lower cost, the single-channel ADS1246 provides a reduced feature set in a TSSOP-16 package for only $3.45.
