Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer designation as Texas Instruments, as National Semiconductor was acquired. Confirm the suffix NOPB indicates lead-free and RoHS compliance. Check the part status, as this specific variant may be obsolete or end-of-life; verify availability through authorized distributors or alternative sources if production has ceased. Ensure the 8-SOIC package dimensions match your PCB footprint requirements.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high slew rate and wide bandwidth are critical for maintaining signal integrity in fast-changing waveforms. Compare against the LM7171AIMX/NOPB variant, which offers similar electrical performance but may differ in temperature range or specific parameter tolerances. Consider the 118 mA output current capability against your load requirements to ensure adequate drive strength without thermal issues.
