NJM2076M#

Overview

The NJM2076M is a Class-AB audio amplifier manufactured by Nisshinbo Micro Devices Inc. It supports 1-channel mono or 2-channel stereo output configurations in an 8-DMP surface-mount package. The device operates on a single power supply with a maximum voltage of 4.5 V and draws a working current of 4.7 mA. It delivers 90 mW of output power into an 8-ohm load or 17.5 mW into two 16-ohm loads. Key electrical parameters include a gain of 28 dB, differential input type, and THD+N of 1.5% or 0.4%. Operating temperature ranges from -20°C to +75°C.

Feature Summary

• Supports flexible mono or stereo audio output configurations
• Operates efficiently at low supply voltages up to 4.5 V
• Features differential input for noise reduction

Applications

• Low voltage portable audio equipment
• Battery-powered consumer electronics
• Mono or stereo audio signal amplification circuits

Procurement Notes

Verify component authenticity as the NJM2076M is listed as discontinued by the manufacturer. Confirm RoHS compliance status through official documentation, as sources indicate non-compliance. Ensure the specific ordering suffix matches the required packaging format, such as tube or reel, before procurement.

Selection Notes

Select this component for applications requiring low-power Class-AB amplification within a 4.5 V limit. Consider the 8-DMP package size for space-constrained designs. Verify that the 28 dB fixed gain meets system requirements without additional external feedback networks.
