NJM2070M-TE1

Overview

The NJM2070M-TE1 is a single-channel Class-AB audio amplifier manufactured by Nisshinbo Micro Devices. It operates on a single power supply ranging from 1.8 V to 15 V and delivers an output power of 600 mW into a 4 Ohm load. The device features a differential input, a gain of 44 dB, and a total harmonic distortion plus noise (THD+N) of 0.25%. It draws a working supply current of 4 mA with an output current capability of 1 A. The component is housed in a DMP-8 surface-mount package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Class-AB topology designed for low voltage single-supply operation
• Differential input configuration supporting high-gain signal processing
• Compact DMP-8 surface-mount package suitable for space-constrained designs

Applications

• Speaker driver circuits
• Low voltage audio systems
• Portable electronic devices requiring mono amplification

Procurement Notes

Verify the specific ordering suffix TE1 against official Nisshinbo documentation to confirm packaging details. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents. Ensure the intended application environment remains within the specified operating temperature limits of -40°C to +85°C. Cross-reference the DMP-8 footprint dimensions with your PCB layout guidelines prior to finalizing the design.

Selection Notes

Select this component when a single-ended Class-AB amplifier is required for driving low-impedance loads such as 4 Ohm speakers. The wide supply voltage range allows compatibility with various battery-powered systems. Verify that the 44 dB fixed gain meets the system requirements without additional external feedback networks. Consider the thermal performance within the DMP-8 package for the expected power dissipation levels.
