ADS1254E/2K5 Description

Short technical summary and product information.

The ADS1254E/2K5 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 19-bit effective resolution at data rates up to 20 kHz. The converter features four differential inputs, an SPI-compatible serial interface, and requires an external reference voltage (0.5V to 5V).

 

Key electrical specifications include a low noise level of 1.8 ppm, integral non-linearity (INL) of 15 ppm maximum, and a power dissipation of only 4 mW at a 20 kHz data rate. The device operates from a separate digital supply of 1.8V to 3.6V and an analog supply range (not specified in the provided data, but typical for this family).

 

The ADS1254E/2K5 is designed for high-resolution measurement applications such as cardiac diagnostics, direct thermocouple interfaces, blood analysis, infrared pyrometers, liquid/gas chromatography, and precision process control. It is housed in a surface-mount 20-SSOP package (0.154", 3.90mm Width) and operates over the industrial temperature range of -40°C to 85°C.
