Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'E/2K5' against official Texas Instruments documentation to confirm the exact package variant and reel quantity specifications. Ensure compatibility with the required operating temperature range of -40°C to +85°C for your intended deployment environment before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit resolution is sufficient for the application's accuracy needs. Consider the ADS7817E/2K5 if the system design mandates differential inputs to reject common-mode noise and requires a compact VSSOP-8 footprint. Verify that the 4.75 V to 5.25 V supply voltage aligns with the available power rails in the target circuit design.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7817 family of micro-power sampling ADCs from Texas Instruments. It shares architectural similarities with other devices in the series but is distinguished by its specific 200 kS/s sampling rate and 12-bit resolution. The E/2K5 designation indicates the commercial temperature grade and the tape-and-reel packaging format used for automated assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

Consult the Texas Instruments ADS7817 datasheet for officially listed pin-compatible or functionally equivalent alternatives. Verify that any substitute maintains the same 12-bit resolution, 200 kS/s speed, and VSSOP-8 package dimensions to ensure seamless integration without PCB redesign.
