Features small size, low power consumption for portable, battery-powered industrial equipment

DALLAS, July 28, 2011 /PRNewswire/ -- Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced the industry's smallest, 16-bit delta-sigma analog-to-digital converter (ADC) with integrated programmable gain amplifier (PGA), reference, temperature sensor and 4-input multiplexer. Measuring 2 mm x 1.5 mm, the ADS1118 is more than 65-percent smaller than any other 16-bit ADC available today. The ADS1118 provides direct, linearized measurements with uncalibrated error guaranteed below 0.5 degrees Celsius ? from 0 degrees C to 65 degrees C, a 75-percent improvement over the competition. It is also the lowest-power 16-bit ADC with a built-in internal reference supporting data rates up to 860 samples per second. For more information and to order samples, visit www.ti.com/ads1118-pr.

Key features and advantages of the ADS1118:

• 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 numerous sensors.
• Small size saves space on the PCB: Small QFN package option allows close proximity to sensors, lowering the number of components by simplifying cold junction compensation for thermocouples.
• Low power consumption extends battery life: Supports 2.0-V 5.5-V power supply and consumes only 150 uA (typical) to extend the battery life of portable, battery-operated devices for industrial temperature measurement, gas monitoring to industrial process control, instrumentation and more .
• Provides a complete data acquisition solutionwhen combined with a MSP430 microcontroller ?.

Tools and Support

TI offers a variety of tools and support for the development with the ADS1118, including an IBIS model, anti-aliasing filtering tool for data converters and operational amplifiers, ADC circuitry to speed up computer topography. 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 immediately for a suggested retail price of $ 49.

Availability, pricing and packaging structure

The ADS1118 is available now in a 5-mm x 3 mm QFN package. Pattern of the 2-mm x 1.5 mm QFN package are also available now with volume expected in December. Both package options are at $ 2.22 in 1,000-unit cost figures.
