Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the package type matches the required PCB footprint, specifically the 14-pin PDIP configuration. Confirm that the supply voltage requirements align with the 3 V to 36 V operational range. Ensure the ambient temperature conditions do not exceed the specified -55 °C to +125 °C limit. Check for any specific handling requirements associated with JFET input devices during assembly.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when multiple low-power amplifiers are needed in a single package. The JFET input stage is suitable for high-impedance sources. Compare the 4.0 MHz bandwidth against application signal frequencies. Consider the 10 V/µs slew rate for dynamic signal requirements. Evaluate the PDIP package for through-hole mounting needs versus surface-mount alternatives.

Instrumentation, Op Amps, Buffer Amps Part Context

The MC34184M is part of onsemi's linear amplifier portfolio, specifically categorized under instrumentation and buffer amplifiers. It serves as a multi-channel solution for applications requiring multiple op-amps without increasing board space significantly. The device complements other low-power analog solutions by offering quad functionality in a standard DIP package.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for pin-compatible quad JFET op-amps with similar bandwidth and power specifications. Verify if alternative packages like SOIC or QFN are available for the same electrical characteristics if surface mount is preferred. Ensure substitute parts maintain the wide supply voltage range and extended temperature rating.
