Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'CN' corresponds to the standard PDIP-14 through-hole package variant. Confirm RoHS compliance status as detailed in the official datasheet documentation. Ensure the ordering part number matches the exact temperature grade and packaging format required for the design. Cross-reference the manufacturer's latest product change notifications for any material or process updates.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a quad amplifier topology is required alongside moderate precision and low power constraints. The 2.2 kHz bandwidth suits applications where speed is secondary to accuracy and stability. Consider the 320 uV offset voltage for DC-coupled signals. Evaluate the 30 mA per-channel output drive against load requirements. Compare against other family members if higher bandwidth or lower noise is necessary.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the TLC279 series of precision operational amplifiers. It utilizes Texas Instruments' proprietary LinCMOS technology, which combines the benefits of CMOS low power with bipolar-like precision. The quad architecture provides multiple amplifier channels in a single footprint, reducing board space compared to individual dual packages.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

TLC279IDR is a documented alternative offering the same functional characteristics in a surface-mount SOIC-14 package. Verify pin compatibility and thermal dissipation differences when transitioning between through-hole and surface-mount technologies.
