ADS7817EB/2K5

Analog To Digital Converters (ADC) Overview

The ADS7817EB/2K5 is a 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a differential input architecture and operates with a sampling rate of 200 kS/s. The device utilizes a 3-wire serial interface compatible with SPI standards. Power consumption is specified at 2.3 mW, supporting operation from a single 5 V supply within the range of 4.75 V to 5.25 V for both analog and digital domains. Nonlinearity performance includes a maximum differential nonlinearity (DNL) of ±1 LSB and integral nonlinearity (INL) of ±2 LSB. The signal-to-noise and distortion ratio (SINAD) is 71 dB. It is housed in an SOIC-8 package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'E' indicates the tape and reel packaging variant when ordering. Confirm that the '/2K5' designation aligns with the required quantity per reel for your manufacturing line. Ensure compatibility with existing 5 V logic levels before finalizing procurement specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 200 kS/s throughput are required with differential inputs. Compare against single-ended variants if common-mode noise is not a primary concern. Verify that the external reference requirement fits within the available board space and budget constraints compared to internal reference alternatives.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7817 family of micro-power ADCs. It shares architectural similarities with the ADS7816 and ADS7819 but differs in input configuration and pinout. The 'E' suffix typically denotes the industrial temperature grade and specific packaging format within the broader product line.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7817UB serves as a tube-packaged alternative within the same functional family. Check datasheet revisions for any pin-compatible upgrades such as the ADS7819, which may offer different input ranges or interface options while maintaining similar performance metrics.
