ADS831E/2K5

Analog To Digital Converters (ADC) Overview

The ADS831E/2K5 is an 8-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a pipelined architecture with a sampling rate of 80 MSPS and supports both single-ended and differential inputs. The device operates on a 5V supply for both analog and digital sections. Key performance metrics include a maximum differential nonlinearity (DNL) of ±1 LSB, a typical DNL of 0.25 ±LSB, and a maximum integral nonlinearity (INL) of 2 ±LSB. The effective number of bits (ENOB) is 7.8 bits, and the analog input bandwidth is 300 MHz. It is housed in a 20-SSOP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range variant (-40°C to 85°C). Confirm the '2K5' packaging designation corresponds to tape-and-reel quantities as specified in the official datasheet. Ensure compatibility with 5V logic levels for the parallel interface. Cross-reference the pinout against the 20-SSOP physical dimensions to prevent mounting errors during PCB assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution at 80 MSPS is sufficient for the application's dynamic range requirements. Consider the 300 MHz analog input bandwidth for signal fidelity. Evaluate the ENOB of 7.8 bits against system noise floors. Choose between internal or external reference options based on precision needs. Ensure the 20-SSOP package fits the available board space and thermal constraints.
