NJM2073M

Overview

The NJM2073M is a dual low voltage power amplifier IC manufactured by Nisshinbo Micro Devices Inc. It operates on a single supply voltage ranging from 1.8V to 15V and delivers up to 2W of output power in bridge-tied load (BTL) configuration with an 8-ohm load at 6V. In stereo mode, it provides approximately 270mW per channel into an 8-ohm load at 5V. The device features a typical operating current of 6mA, a closed-loop voltage gain of 44dB, and total harmonic distortion of 0.2%. It utilizes bipolar technology and is housed in an 8-DMP surface-mount package.

Feature Summary

Supports both bridge-tied load and stereo configurations for flexible audio system design
Operates effectively with low crossover distortion and eliminates turn-on noise
Maintains low operating current suitable for battery-powered portable devices

Applications

Portable radio systems
Handy cassette players
Low voltage audio power amplification circuits

Procurement Notes

Verify the specific suffix 'M' indicates the DMP8 surface-mount package variant rather than the DIP8 through-hole version. Confirm RoHS compliance status as distributor records may vary. Check lead times and availability as this component may be subject to discontinuation or limited stock constraints.

Selection Notes

Select this component when designing portable audio equipment requiring dual-channel amplification within a compact footprint. Ensure the application supports the specified 1.8V to 15V single-supply range. Consider the thermal dissipation limits of the DMP8 package if operating near maximum power levels.

Part Context

This part belongs to the NJM2073 series of dual low voltage power amplifiers. It is designed specifically for portable consumer electronics where space and power efficiency are critical. The M suffix denotes the plastic DMP8 package format, distinguishing it from the standard DIP8 variant.
