NJM2070M-TE3

Overview

The NJM2070M-TE3 is a single-channel Class-AB audio amplifier manufactured by Nisshinbo Micro Devices. It delivers 600 mW of output power into a 4 Ohm load with a total harmonic distortion plus noise of 0.25%. The device operates on a single power supply ranging from 1.8 V to 15 V and draws a typical operating current of 4 mA. Key electrical parameters include a gain of 44 dB, an input bias current of 200 nA, and a maximum output current of 1 A. It supports differential inputs and features a DMP-8 surface-mount package suitable for applications operating between -40°C and +85°C.

Feature Summary

• Class-AB topology designed for low voltage operation
• Differential input configuration for improved noise rejection
• Single-ended output architecture

Applications

• Speaker driving in portable electronic devices
• Low voltage audio signal amplification
• Battery-powered consumer electronics

Procurement Notes

Verify the specific ordering suffix TE3 against official Nisshinbo documentation to confirm RoHS compliance and tape-and-reel packaging specifications. Ensure the DMP-8 footprint matches your PCB design constraints. Cross-reference the manufacturer part number NJM2070M-TE3 directly with authorized distributors to confirm current availability status and lead times, as distribution channels may vary by region.

Selection Notes

Select this component when a single-channel, low-voltage Class-AB amplifier is required for driving low-impedance loads such as 4 Ohm speakers. The differential input capability makes it suitable for noisy environments where common-mode noise rejection is necessary. Verify that the 1.8 V minimum supply voltage aligns with your system's battery or power rail requirements and that the 44 dB gain meets your signal chain needs without excessive external attenuation.

Part Context

The NJM2070 series belongs to Nisshinbo Micro Devices' portfolio of audio integrated circuits. This specific model is engineered for compact, battery-operated applications requiring efficient audio amplification within a small DMP-8 package. It represents a solution for designers needing a balance of moderate power output, low quiescent current, and robust performance in space-constrained consumer electronics designs.

Replacement Considerations

Consult official Nisshinbo cross-reference guides for verified substitute part numbers. Do not assume pin-compatible alternatives from other manufacturers without verifying electrical parameter alignment and thermal characteristics.
