Overview
The NJM386BM-TE1 is a low voltage audio amplifier manufactured by Nisshinbo Micro Devices Inc. It operates as a Class-AB single-channel mono amplifier housed in an SMD/SMT DMP-8 package. The device supports a supply voltage range from 4 V to 12 V and delivers 500 mW of output power into a 16 Ohm load. Key electrical parameters include a gain of 46 dB, a total harmonic distortion plus noise (THD+N) of 0.2%, and a quiescent current of 3 mA. It features differential input with an input bias current of 250 nA. The component functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Class-AB topology for efficient audio amplification
- Low voltage operation capability
- Single-channel mono output configuration
Applications
- Low voltage audio systems
- Portable electronic devices requiring mono amplification
Procurement Notes
This product is designated as a discontinued item by the manufacturer. Production will cease in the near term, and availability is restricted to customers currently utilizing this component. It is not available for new project designs. Procurement should be verified through official sales channels or authorized distributors, keeping in mind that supply is limited and time-bound. Confirm end-of-life status before finalizing any orders.
Selection Notes
Select this component only if it is required for existing maintenance or replacement purposes due to its discontinued status. For new designs, consider alternative active products from the manufacturer. Verify that the DMP-8 surface mount package and 4V to 12V supply range align with the system requirements. Ensure the 500 mW output power at 16 Ohms meets the application needs.
Part Context
The NJM386B series includes variants such as the NJM386M and NJM386BM, which share similar Class-AB audio amplifier characteristics but may differ in specific electrical parameters like output power and input type. The NJM386BM-TE1 specifically denotes the TE1 tape and reel packaging variant of the NJM386B family. This series is part of Nisshinbo's portfolio of low voltage audio solutions.
Replacement Considerations
Due to the discontinued status, direct substitutes are not officially confirmed in the provided documentation. Designers should consult the manufacturer for recommended active replacements suitable for new projects.
