The ADS1251U is a precision, wide dynamic range, delta-sigma analog-to-digital converter (ADC) from Texas Instruments. It offers 24-bit resolution with no missing codes and achieves an effective resolution of 19 bits (1.5ppm rms noise) at conversion rates up to 20ksps. The device operates from a single +5V supply with an analog supply range of 4.75V to 5.25V and a digital supply range of 4.75V to 5.25V.
This ADC features a differential input, external voltage reference, and an SPI data interface. It includes 50/60 Hz rejection for improved noise performance in industrial environments. The sigma-delta architecture provides wide dynamic range suitable for high-resolution measurement applications. Typical power consumption is 7.5mW at 20ksps, with lower power modes available.
The ADS1251U is housed in an 8-SOIC surface-mount package with an operating temperature range of -40°C to +85°C. It is designed for applications including cardiac diagnostics, direct thermocouple interfaces, blood analysis, infrared pyrometers, liquid/gas chromatography, and precision process control.
