CA3420E

Overview

The CA3420E is a single-channel general-purpose operational amplifier manufactured by Renesas Electronics Corporation. It features an 8-PDIP package with through-hole mounting. Key electrical specifications include a supply voltage range of 2 V to 20 V, a maximum output swing of 2 V, and a typical supply current of 450 µA. The device offers a gain-bandwidth product of 500 kHz, a slew rate of 0.5 V/µs, and an input offset voltage of 5 mV. Input bias current is specified at 0.05 pA, with an output current capability of 2.6 mA per channel. It operates within a temperature range of -55°C to 125°C.

Feature Summary

• Single-channel standard operational amplifier configuration
• Full-swing output capability for signal integrity
• Low power consumption suitable for battery applications
• Wide operating temperature range for industrial environments

Applications

• General-purpose analog signal conditioning circuits
• Sensor interface amplification stages
• Active filter implementations
• Buffering applications in instrumentation systems

Procurement Notes

Verify component authenticity as the CA3420E is officially obsolete and no longer manufactured by Renesas Electronics Corporation. Confirm that any available units are genuine surplus stock rather than counterfeit replacements. Check for direct substitute part numbers such as the CA3420EZ if new production availability is required. Ensure compliance with RoHS directives if applicable to the end application, noting this specific variant may not meet current environmental standards.

Selection Notes

Select this component only for legacy system maintenance or repair where original part matching is critical. Evaluate the CA3420EZ as a potential direct replacement from the same manufacturer. Consider modern equivalents if new design implementation is possible, given the obsolete status. Verify pin compatibility and electrical parameter alignment before substitution in existing circuit designs.

Part Context

The CA3420E belongs to the CA3420 family of operational amplifiers produced by Renesas Electronics Corporation. It is classified as a standard general-purpose amplifier housed in an 8-pin dual in-line package. The component represents older semiconductor technology compared to contemporary low-power or high-speed alternatives. Its discontinuation reflects industry shifts toward newer fabrication processes and updated product lines.

Replacement Considerations

The CA3420EZ is listed as a direct substitute part number from Renesas Electronics Corporation.
