NJM386M

Overview

The NJM386M is a low-voltage Class-AB audio amplifier manufactured by Nisshinbo Micro Devices. It provides 500 mW of output power into a 16 Ohm load with a total harmonic distortion plus noise of 0.2%. The device operates on a single power supply ranging from 4 V to 12 V and draws a working supply current of 3 mA. It features a differential input type, a gain of 46 dB, and an input bias current of 250 nA. The component is housed in an 8-pin DMP package and supports surface mount installation.

Feature Summary

Applications

• Low voltage audio systems
• Portable audio devices

Procurement Notes

This component is designated as a discontinued product by the manufacturer. Production will cease in the near term, and availability is restricted to existing customers for a limited time only. It is not approved for use in new projects. Buyers must verify current stock status and lead times directly with authorized distributors or sales offices before initiating any procurement actions.

Selection Notes

Engineers should evaluate this part only for maintenance or replacement within existing designs. Due to its discontinuation status, it is unsuitable for new product development. Designers requiring long-term supply stability should select alternative audio amplifiers from the manufacturer's current portfolio that offer similar electrical specifications and packaging options.

Part Context

The NJM386M belongs to the NJM386 series of low-voltage audio amplifiers produced by New Japan Radio Co., Ltd., now Nisshinbo Micro Devices. This series is designed for applications requiring efficient audio amplification under constrained power supply conditions. The specific M suffix indicates the surface-mount DMP package variant.
