ADS1216Y_integrated Circuits, 24-Bit ANALOG-TO-DIGITAL CONVERTER

The ADS1216y is a precision, wide dynamic range,delta-sigma, Analog-to-Digital (A/D) converter with 24-bit resolution operating from 2.7V to 5.25V supplies. The delta-sigma A/D converter provides up to 24 bits of no-missing-code performance and an effective resolution of 22 bits. The eight input channels are multiplexed. Internal impedance for direct connection to transducers or low-level voltage signals.Burnout current sources are provided that allow for the detection of an open or shorted sensor. An 8-bit Digital-to-Analog 0.1V to 2.5V Converter (DAC) provides an offset correction with a range of 50% of the FSR (Full-Scale Range). The PGA (Programmable Gain Amplifier) provides selectable gains of 1 to 128 with an effective resolution of 19 bits at a gain of 128. The A/D conversion is accomplished with a second-order delta-sigma modulator and programmable sinc filter. ADS1216y APPLICATIONS • INDUSTRIAL PROCESS CONTROL • LIQUID/GAS CHROMATOGRAPHY • BLOOD ANALYSIS • SMART TRANSMITTERS • PORTABLE INSTRUMENTATION • WEIGHT SCALES • PRESSURE TRANSDUCERS This integrated circuit can be damaged by ESD.Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
