ADS1254E Description

Short technical summary and product information.

The ADS1254E is a precision 24-bit delta-sigma analog-to-digital converter (ADC) from Texas Instruments. It achieves 24 bits of no missing codes performance with an effective resolution of 19 bits and low noise of 1.8 ppm RMS. The device operates at a maximum sampling rate of 20 kSPS and features four differential input channels via an integrated multiplexer.

 

The ADC uses an external reference (0.5V to 5V) and includes 50/60 Hz rejection for improved noise performance. It requires separate analog (4.75V to 5.25V) and digital (1.8V to 3.6V) power supplies, consuming only 4.3 mW typical power. The SPI interface enables easy connection to microcontrollers and digital systems.

 

The ADS1254E is housed in a 20-SSOP surface-mount package (8.65 mm × 6 mm) and operates over the industrial temperature range of -40°C to 85°C. Typical applications include cardiac diagnostics, direct thermocouple interfaces, blood analysis, infrared pyrometers, liquid/gas chromatography, and precision process control.
