Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix /250 indicates a 250-unit small tape and reel carrier configuration as documented in the Package Option Addendum. Confirm RoHS compliance status and lead finish specifications (NIPDAU) match project requirements. Ensure the SOT-23-8 package designation aligns with PCB footprint designs. Cross-reference the active production status to confirm availability for manufacturing.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when dual-channel amplification is required in space-constrained designs. The SOT-23-8 package provides a compact solution compared to larger formats. Consider the 350kHz bandwidth limit for signal processing needs. The low quiescent current makes it appropriate for energy-efficient systems. Verify that the rail-to-rail input transition region characteristics fit the application's common-mode voltage requirements.

Instrumentation, Op Amps, Buffer Amps Part Context
