CA0258AE

Instrumentation, Op Amps, Buffer Amps Overview

The CA0258AE is a dual operational amplifier manufactured by Harris Corporation, designed for commercial, industrial, and military applications. It features two independent, high-gain, internally frequency-compensated amplifiers capable of operating from a single power supply over a wide voltage range or from split supplies. The device offers a typical unity-gain bandwidth of 1MHz and a high DC voltage gain of 100dB. It operates with a low supply current of 1.5mA, which remains largely independent of the supply voltage within recommended ranges. Input common-mode voltage includes ground, and it provides a large output voltage swing.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Internally frequency compensated for stability in unity-gain configurations
• Capable of operation from single or split power supplies
• High DC voltage gain suitable for precision amplification
• Low supply current consumption independent of supply voltage

Instrumentation, Op Amps, Buffer Amps Applications

• Interface circuits with digital systems
• Transducer amplifiers
• DC gain blocks

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer origin carefully, as the CA258 designation is widely used by multiple vendors including Intersil and others. Confirm that the specific CA0258AE suffix corresponds to the intended Harris Corporation specification and performance characteristics. Ensure compatibility with required supply voltage ranges and environmental conditions before integration into the design.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual op-amp solution is required for single-supply operation with ground-referenced inputs. Its internal frequency compensation simplifies circuit design by ensuring stability without external components. Consider its 1MHz bandwidth and 100dB gain for general-purpose analog signal processing tasks where moderate speed and high accuracy are needed.

Instrumentation, Op Amps, Buffer Amps Part Context

The CA258 series consists of dual operational amplifiers equivalent to industry-standard types like the 158, 258, and 358. These devices are designed for versatility, supporting both single and dual supply configurations. They are commonly used in applications benefiting from single-supply capability, such as interfacing with digital logic systems powered by 5VDC.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The CA0258AE is functionally equivalent to or a replacement for industry types 158, 158A, 258, 258A, 358, 358A, and CA2904. Verify pinout and electrical specifications against the specific datasheet of the target replacement part to ensure compatibility.
