Procurement Notes

Verify the specific manufacturer suffix and date code against official onsemi documentation to ensure component authenticity. Confirm that the package type matches the required 14-pin DIP configuration for your PCB layout. Check RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the operating temperature range meets your system's thermal requirements.

Selection Notes

Select this component when multiple low-cost, general-purpose amplification stages are required in a single footprint. It is suitable for applications where high precision is not critical but cost efficiency and simplicity are priorities. Consider the 1.5 mV input offset voltage and 250 nA bias current limits to ensure they fit your signal chain accuracy requirements.
