Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer designation as Harris Corporation or its successor entities, such as Intersil or Renesas, due to corporate acquisitions. Confirm the suffix 'S' corresponds to the 8-SOIC package variant. Ensure the component meets the specific temperature grade required for your application environment before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a balance between low quiescent current and moderate speed is required. The BiMOS architecture offers high input impedance suitable for sensitive sensor interfaces. Consider the 8-SOIC package constraints regarding thermal dissipation and board space availability during the design phase.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the CA34xx series of Nanopower BiMOS operational amplifiers. The series is characterized by the integration of MOSFET inputs for high impedance and bipolar outputs for drive capability. The CA3440 represents the single-channel configuration within this family, distinct from dual or quad variants like the CA3420 or CA3410.
