Fully integrated ADC targets portable equipment
It provides direct, linearised measurements with uncalibrated error guaranteed below 0.5degC from 0c to 65c; claiming a 75 percent improvement over its competition. It is also said to be the lowest power 16bit ADC with a built-in internal reference, supporting data rates up to 860 samples/s.
TI is providing a number of tools and support for the device, 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. The datasheet can be downloaded from www.ti.com
