Texas Instruments has 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 (C) 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-preu.

Provides small size, low power consumption for portable, battery-powered industrial devices

Key features and benefits 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 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 2.0-V to 5.5-V 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.

Tools and support

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 today for a suggested retail price of $49.
