NJM2770M

Overview

The NJM2770M is a Class-AB audio amplifier manufactured by Nisshinbo Micro Devices. It provides 400 mW of output power into a 16 Ohm load. The device operates on a single supply voltage ranging from 2 V to 4.5 V. Total Harmonic Distortion plus Noise (THD+N) is specified at 0.1%. The input stage utilizes a differential configuration with an input bias current of 100 nA. Operating quiescent current is 2 mA. The component functions within a temperature range of -40°C to +85°C and is housed in a VSP-8 surface-mount package.

Feature Summary

• Class-AB topology for efficient audio amplification
• Low voltage operation capability down to 2 V
• Differential input interface design

Applications

• Portable audio devices
• Battery-powered consumer electronics
• Compact speaker systems

Procurement Notes

Verify the specific suffix against official documentation, as packaging variations may exist. Confirm RoHS compliance status through the manufacturer's latest datasheet or product notification. Ensure the VSP-8 footprint matches your PCB layout requirements before finalizing procurement decisions.

Selection Notes

Select this component when low-voltage operation and moderate power output are required. The differential input simplifies circuit design compared to single-ended alternatives. Verify that the 16 Ohm load impedance aligns with your speaker specifications to achieve the rated 400 mW performance.

Part Context

This part belongs to the NJM2770 series of audio amplifiers. It shares functional similarities with other low-power audio ICs in the manufacturer's portfolio but is distinct in its specific Class-AB architecture and VSP-8 packaging constraints.

Replacement Considerations

Consult official substitution lists for verified equivalents. Generic replacements may differ in pinout or electrical characteristics.
