Procurement Notes

Verify the specific package configuration when ordering, as the BE1D suffix indicates dice (wafer sawn) format typically supplied in waffle packs. Confirm availability with authorized distributors, as stock levels may be limited. Ensure compatibility with ECAD tools if simulation models are required for design integration. Check for any specific handling requirements associated with bare die components during assembly.

Selection Notes

Select the ZSSC3138BE1D when designing systems requiring precise amplification and correction of resistive bridge sensors without laser trimming. It is suitable for applications demanding high long-term stability and traceability through user-defined EEPROM entries. Consider this part for environments requiring operation up to +150°C and protection against reverse polarity and short circuits.
