Industry’s smallest, fully integrated 16bit ADC
20 September 2011
This ADC provides low power consumption for portable, battery-powered industrial devices.
Texas Instruments has introduced to the market the industry’s smallest, 16bit delta-sigma analogue-to-digital converter with integrated programmable gain amplifier (PGA), reference, temperature sensor and 4-input multiplexer.
Measuring 2mm x 1.5mm, the ADS1118 is, according to the manufacturer, over 65% smaller than any other 16bit ADC available.
ADS1118 provides direct, linearised measurements with uncalibrated error guaranteed below 0.5°C from 0°C to 65°C. It is also the lowest-power 16-bit ADC with a built-in internal reference supporting data rates up to 860 samples per second.
Key features and benefits of the ADS1118 include:
• Integration reduces overall solution size: Integrates a 16-bit ADC, PGA, temperature sensor, low-drift reference and 4-input multiplexer for data acquisition of multiple signals from a wide variety of sensors.
• Small size saves board space: Small QFN package option enables close proximity to sensors, lowering component count by simplifying cold junction compensation for thermocouples.
• Low power extends battery life: Supports 2.0V to 5.5V power supplies while consuming only 150 uA (typical) to extend the battery life of portable, battery-powered industrial devices for temperature measurement, gas monitoring, industrial process control, instrumentation and more.
• Provides a complete data acquisition solution when paired with an MSP430 microcontroller.
TI offers a variety of tools and support to speed development with the ADS1118, including an IBIS model, anti-aliasing filter tool for data converters and op amp to ADC circuit topography calculator. Engineers can also ask questions and help solve problems in the Precision Data Converter Forum in the TI E2E Community.
An evaluation module (ADS1118EVM), including software and source code, is available too.
The ADS1118 is available now in a 5mm x 3mm MSOP package. Samples of the 2mm x 1.5mm QFN package are also available with production quantities expected in December.
