Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer marking indicates National Semiconductor or Texas Instruments to ensure authenticity. Confirm the package type is 14-SOIC and the suffix MX denotes the tape-and-reel variant. Check for date codes consistent with current production standards. Ensure the component meets the specified commercial temperature range requirements for your specific application environment.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when multiple op-amps are required in a space-constrained design. It is suitable for applications requiring moderate bandwidth and drive strength. Consider the 14-SOIC footprint for PCB layout compatibility. Verify that the 3V to 36V supply range aligns with the system power architecture. Evaluate thermal performance if multiple channels are heavily loaded simultaneously.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LM340x series of quad operational amplifiers. It is a legacy product from National Semiconductor, which was acquired by Texas Instruments. The series offers a cost-effective solution for multi-channel analog signal processing tasks in standard industrial and consumer markets.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible substitutes may include other quad op-amps from the same family or equivalent parts from other manufacturers such as TL084 variants, provided electrical specifications match.
