Kit Overview

The Texas Instruments ADS1118EVMADS1118EVM is a complete solution for evaluation of the ADS1118ADS1118 Ultra-Small, Low Power,Precision 16 Bit Analog to Digital Converter. Power and I/O are provided via USB connection and a simple software interface. Inputs for a thermocouple are provided on board, plus two additional uncommitted inputs are available. This evaluation module (EVM) allows evaluation of all aspects of the ADS1118IDGSTADS1118IDGST, a 16-bit, delta-sigma analog-to-digital converter (ADC)

ADS1118ADS1118 16-Bit ADC with Integrated MUX, PGA, Temperature Sensor, Oscillator, and Reference:

The ADS1118IDGSTADS1118IDGST is a precision ADC.
It features onboard reference and oscillator, as well as 16 bits of resolution.
The ADS1118IDGSTADS1118IDGST can perform up to 860 samples per second (SPS) and has an onboard programmable gain amplifier (PGA) that allows input ranges from ±256 mV to ±6.144 V.
It also contains an input multiplexer that allows each input to be used with reference to ground, or two differential inputs.
The ADS1118IDGSTADS1118IDGST can perform conversions at rates up to 860 samples per second (SPS).
An onboard programmable gain amplifier (PGA) is available on the ADS1118IDGSTADS1118IDGST that offers input ranges from the supply to as low as ±256mV. This range allows both large and small signals to be measured with high resolution.
The ADS1118IDGSTADS1118IDGST also features an input multiplexer (MUX) that provides two differential or four single-ended inputs.
The ADS1118IDGSTADS1118IDGST can also function as a high-accuracy temperature sensor. This temperature sensor can be used for system-level temperature monitoring or cold junction compensation for thermocouples.
The ADS1118IDGSTADS1118IDGST operates either in continuous conversion mode or a single-shot mode that automatically powers down after a conversion. Single-shot mode significantly reduces current consumption during idle periods. The ADS1118 is specified from –40°C to +125°C.

Key Applications: Temperature Measurement(Thermocouple Measurement, Cold Junction Compensation, Thermistor Measurement), Portable Instrumentation, Factory Automation and Process Controls
