NJM4565DD

Overview

The NJM4565DD is a dual operational amplifier manufactured by Nisshinbo Micro Devices. It features a gain-bandwidth product of 10 MHz and a slew rate of 4 V/µs. The input offset voltage is specified at a maximum of 3 mV, with an input bias current of 200 nA. Operating on supply voltages between 4 V and 18 V, the device draws 7 mA of quiescent current per channel. It offers a common-mode rejection ratio of 70 dB and functions within a temperature range of -40°C to +85°C. The component utilizes bipolar technology and is housed in an 8-pin PDIP package.

Feature Summary

• Dual-channel architecture providing two independent voltage-feedback amplifiers in a single package.
• Bipolar process technology ensures stable performance across standard industrial temperature ranges.
• Low noise design characteristics suitable for signal conditioning applications.

Applications

• General-purpose analog signal amplification
• Audio pre-amplifier stages
• Sensor signal conditioning circuits

Procurement Notes

Verify the specific suffix DD indicates the PDIP-8 package configuration when sourcing. Confirm RoHS compliance status as some legacy listings may vary. Check for NRND (Not Recommended for New Designs) status if available in official manufacturer catalogs to assess long-term availability risks before finalizing procurement plans.

Selection Notes

Select this component when a dual op-amp solution is required with moderate bandwidth and low power consumption. The 10 MHz gain-bandwidth product supports audio frequency applications effectively. Ensure the circuit design accommodates the 3 mV maximum input offset voltage and 200 nA bias current specifications for optimal accuracy.

Part Context

This part belongs to the NJM4565 series of dual operational amplifiers from Nisshinbo Micro Devices. The series includes variants such as NJM4565D and NJM4565MD, differing primarily in packaging formats like DIP or surface-mount options while maintaining identical electrical performance characteristics defined by the core bipolar amplifier design.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pin compatibility and electrical parameters against alternative dual op-amps if direct substitution is required.
