The ADS1251U is a precision, 24-bit Analog-to-Digital Converter (ADC) from ADI Electronics, designed for wide dynamic range measurements. Utilizing a delta-sigma architecture, it guarantees 24 bits of no missing codes performance. The device achieves an effective resolution of 19 bits with low noise (1.5ppm) at conversion rates up to 20 kSPS.
Key electrical specifications include a differential input type, SPI interface, and support for external reference voltages from 0.5V to 5V. It operates with analog and digital supply voltages ranging from 4.75V to 5.25V. The ADC features 50/60 Hz rejection, power-down mode, and sync mode.
Packaged in an 8-pin SOIC with dimensions of 4.9 mm x 6 mm, the ADS1251U is suitable for applications requiring high-resolution data acquisition. Its operating temperature range is -40°C to 85°C. Typical power consumption is 7.5mW at 20 kSPS.
Applications include cardiac diagnostics, direct thermocouple interfaces, blood analysis, infrared pyrometers, liquid/gas chromatography, and precision process control.
