Overview
The CA3440T is a single-channel operational amplifier manufactured by Harris Corporation, housed in an 8-pin TO-99 metal can package. It integrates MOS and bipolar transistors on a monolithic chip to combine the advantages of both technologies. Key electrical specifications include a gain-bandwidth product of 63 kHz, an input bias current of 10 pA, and an input offset voltage of 5 mV. The device features a slew rate of 0.3 V/µs.
Feature Summary
- Combines MOS and bipolar transistor advantages on a single monolithic chip
- Designed for precision applications requiring low input current
- General-purpose amplifier configuration with one circuit
Applications
- Precision instrumentation circuits
- Low-level signal amplification
- High-impedance sensor interfaces
Procurement Notes
Verify the manufacturer origin, as Harris Corporation has undergone corporate changes and mergers. Confirm that the specific part number CA3440T corresponds to the intended TO-99-8 package variant. Ensure compatibility with legacy system requirements if sourcing from secondary markets or surplus distributors.
Selection Notes
Select this component when low input bias current and moderate bandwidth are required. The BiMOS technology offers a balance between high input impedance and robust output drive capability. Consider the TO-99 package for environments requiring hermetic sealing or superior thermal performance compared to plastic packages.
Part Context
Harris Corporation specialized in communications and information technology before merging with L3 Technologies to form L3Harris Technologies. The CA3440 series belongs to a family of BiMOS operational amplifiers designed for mixed-signal applications, leveraging the high input impedance of MOSFETs and the drive strength of bipolar outputs.
Replacement Considerations
Publicly confirmed substitute part numbers for the CA3440T are not available in the provided documentation. Verify pinout and electrical characteristics against potential alternatives such as other BiMOS op-amps from Intersil or Renesas, which acquired related assets.
