Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix /3K indicates reel packaging when ordering. Confirm the SOT-23-5 package type matches your PCB footprint requirements. Ensure the 2.5 V to 5.5 V supply voltage range aligns with your system design. Check humidity sensitivity levels for proper storage and handling procedures during assembly.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring low power consumption and rail-to-rail operation within a compact SOT-23-5 package. Consider the 1 MHz bandwidth and 800 mV/us slew rate for moderate-speed signal processing tasks. Evaluate the 150 uA supply current against battery life requirements. Compare input offset voltage specifications if higher precision is needed for your specific application.
