CA3493E

Overview

The CA3493E is a single-channel general-purpose operational amplifier manufactured by Harris Corporation. It utilizes BiMOS technology to deliver precision performance in an 8-pin PDIP package. Key electrical specifications include a gain bandwidth product of 1.2 MHz, a slew rate of 0.25 V/µs, and a supply current of 2.3 mA. The device supports a minimum supply voltage span of 36 V and operates within a temperature range of 0°C to 70°C.

Feature Summary

• BiMOS precision operational amplifier architecture
• Single circuit configuration for general-purpose applications
• Low input bias current characteristics

Applications

• General-purpose signal amplification
• Precision analog signal processing
• Buffer amplifier circuits

Procurement Notes

Verify the manufacturer designation as Harris Corporation when sourcing this component. Confirm the specific suffix 'E' corresponds to the standard operating temperature range and package type. Ensure compatibility with through-hole mounting requirements for your PCB design. Cross-reference part numbers carefully to distinguish between similar variants in the CA3493 series.

Selection Notes

Select the CA3493E for applications requiring a single op-amp with moderate bandwidth and low power consumption. Its BiMOS construction offers a balance of speed and precision suitable for general-purpose tasks. Consider the 8-PDIP package for prototyping or legacy systems requiring through-hole integration. Evaluate the 1.2 MHz gain-bandwidth product against your signal frequency requirements.

Part Context

This component belongs to the CA3493 series of BiMOS precision operational amplifiers produced by Harris Corporation. The series typically includes multiple channels and package options, with the CA3493E representing the single-channel variant. These amplifiers are designed for applications demanding stable performance and low power operation within standard industrial temperature ranges.

Replacement Considerations

Consult official datasheets for direct pin-compatible substitutes from Harris or other manufacturers. Verify that alternative components match the 1.2 MHz gain bandwidth product and 2.3 mA supply current specifications. Ensure the replacement supports the same 8-PDIP package and 0°C to 70°C operating temperature range.
