ADS1252U/2K5 Description

Short technical summary and product information.

The ADS1252U/2K5 is a precision 24-bit Sigma-Delta analog-to-digital converter (ADC) from Texas Instruments. It operates from a single +5V supply and achieves 24 bits of no missing code performance. The converter provides an effective resolution of 19 bits with low noise of 2.5ppm RMS.

 

Key specifications include a maximum sample rate of 41kSPS (typical 40kSPS), a single differential input channel, SPI data interface, and external reference. The analog and digital supply voltage range is 4.75V to 5.25V. Typical power consumption is 40mW. Integral nonlinearity is 0.0015% maximum.

 

The device includes features such as 50/60 Hz rejection, power-down mode, and SYNC mode. It is designed for high-resolution measurement applications including cardiac diagnostics, direct thermocouple interfaces, blood analysis, infrared pyrometers, liquid/gas chromatography, and precision process control.

 

The ADC is available in an 8-SOIC surface-mount package (8-SOIC, 0.154" width, 3.90mm width). Operating temperature range is -40°C to 85°C. The device is RoHS3 compliant and has MSL 1 (unlimited) moisture sensitivity level.
