Procurement Notes

Verify the specific suffix 'QML' indicates qualification to military or aerospace standards as defined by National Semiconductor documentation. Confirm that the package type matches the required board layout, typically SOIC-8. Ensure the operating temperature range aligns with the specified industrial or extended limits in the official datasheet before finalizing procurement orders.

Selection Notes

Select this component when high bandwidth and low distortion are critical requirements. The voltage feedback architecture allows flexibility in resistor selection without stability constraints typical of current feedback amplifiers. Consider the 70 mW power dissipation for thermal management in compact designs requiring high slew rates and wide dynamic range.

Part Context

This part belongs to the CLC405 series of high-speed operational amplifiers from National Semiconductor. It combines the properties of Comlinear’s current feedback amplifiers with a classical voltage feedback architecture. The QML designation suggests it meets specific quality and reliability standards beyond standard commercial grades, suitable for demanding environments.

Replacement Considerations

Direct replacements must match the 750 MHz bandwidth and 70 mW power profile. Verify pin compatibility if substituting with other CLC405 variants. Ensure any alternative device supports the same dual or single supply operation and maintains similar noise and offset specifications.
