Analog To Digital Converters (ADC) Procurement Notes

This component has been officially declared obsolete and is no longer in production. Verification of availability should focus on the designated parameter-equivalent substitute, ADS805E, which remains listed by the manufacturer. Procurement strategies must account for the end-of-life status by prioritizing alternative sourcing channels or design modifications to incorporate the recommended replacement part.

Analog To Digital Converters (ADC) Selection Notes

Designers requiring this specific performance profile should evaluate the ADS805E as the primary functional equivalent. Selection criteria must align with the original specifications, including the 12-bit resolution, 20 MSPS throughput, and 28-SSOP footprint. Engineers should verify that the substitute part meets all electrical and mechanical requirements for the target application before finalizing the bill of materials.

Analog To Digital Converters (ADC) Part Context

The ADS805EG4 belongs to the ADS805 family of high-speed analog-to-digital converters. The 'G4' suffix typically denotes lead-free packaging compliant with RoHS standards. As a member of this series, it shares core architectural characteristics with other variants in the line, providing a standardized solution for mid-range speed data conversion tasks within Texas Instruments' portfolio.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS805E is identified as a parameter-equivalent substitute for the ADS805EG4. This replacement maintains the same functional specifications and pinout compatibility, facilitating direct integration into existing designs without requiring schematic changes.
