CA0358AM

Overview

The CA0358AM is a dual operational amplifier manufactured by Harris Corporation, housed in an 8-SOIC package. It features two independent circuits with a gain-bandwidth product of 1 MHz and a supply current of 1.5 mA per circuit. Key electrical specifications include an input bias current of 45 nA and an input offset voltage of 2 mV. The device supports an output current of 40 mA per channel and is classified as a general-purpose amplifier suitable for commercial and industrial applications.

Feature Summary

• Dual operational amplifier configuration providing two independent signal processing channels within a single integrated circuit.
• General-purpose design optimized for standard linear amplification tasks across commercial and industrial environments.
• Low power consumption characteristics enabled by a supply current of 1.5 mA, supporting energy-efficient system designs.

Applications

• Commercial electronic equipment requiring general-purpose signal conditioning
• Industrial control systems utilizing low-power analog processing
• Military-grade applications compatible with the CA358A specification family

Procurement Notes

Verify RoHS compliance status carefully, as sources indicate conflicting information regarding lead-free certification for this specific part number. Confirm the manufacturer source is Harris Corporation or its authorized successors, such as L3Harris, to ensure authenticity. Check for any ordering suffixes that may affect pinout or performance specifications before finalizing procurement orders.

Selection Notes

Select the CA0358AM when a dual-channel solution is required with moderate bandwidth and low quiescent current. It serves as a direct functional replacement for the industry-standard LM358 architecture. Ensure the application does not require rail-to-rail output swing, as this device utilizes standard bipolar output stages. Verify package compatibility with existing 8-SOIC footprints during PCB layout validation.

Part Context

This component belongs to the broader family of dual operational amplifiers derived from the classic 358 topology. It shares functional similarities with the CA358A, which covers commercial, industrial, and military temperature ranges. The CA0358AM specifically denotes the commercial/industrial variant packaged in surface-mount technology, maintaining compatibility with legacy through-hole designs while enabling automated assembly processes.

Replacement Considerations

The CA358A is a confirmed substitute part number offering similar dual-channel functionality with extended environmental ratings. Other generic dual op-amps like the LM358 may provide pin-compatible alternatives if sourcing constraints exist, though electrical parameters should be cross-referenced against the original datasheet requirements.
