Product Summary
The ADS1251U is a precision, wide dynamic range, deltasigma, Analog-to-Digital (A/D) converter with 24-bit resolution operating from a single +5V supply. The ADS1251U features wide dynamic range, and 24 bits of no missing code performance. Effective resolution of 19 bits (1.5ppm of rms noise) is achieved at conversion rates up to 20kHz. The ADS1251U is designed for high-resolution measurement applications in cardiac diagnostics, smart transmitters, industrial process control, weigh scales, chromatography, and portable instrumentation.The applications of the ADS1251U include cardiac diagnostics, direct thermocouple interfaces, blood analysis, infrared pyrometers, liquid/gas chromatography and precision process control.
