Product Summary
The ADS1218Y/250 is an 8-Channel, 24-Bit analog-to-digital converter with flash memory. It provides an offset correction with a range of 50% of the FSR (Full-Scale Range). The on-board current ADS1218Y/250 (Digital-to-Analog Converter) operates independently with the maximum current set by an external resistor. It is designed for high-resolution measurement applications in smart transmitters, industrial process control, weight scales, chromatography, and portable instrumentation. The applications of the ADS1218Y/250 are industrial process control, liquid/gas chromatography, blood analysis, smart transmitters, portable instrumentation, weight scales, pressure transducers.
