NJM2076M-TE1

Overview

The NJM2076M-TE1 is a dual low-voltage Class-AB audio amplifier manufactured by Nisshinbo Micro Devices. It supports mono or stereo configurations with a maximum output power of 90 mW into an 8-ohm load and 17.5 mW into a 16-ohm load. The device operates on a single supply voltage ranging from 1.8 V to 4.5 V, drawing a typical quiescent current of 4.7 mA. Key electrical parameters include a fixed gain of 28 dB, differential input capability, and a total harmonic distortion plus noise (THD+N) of 1.5% at 90 mW output. The component is housed in an 8-DMP surface-mount package.

Feature Summary

• Dual-channel architecture supporting both mono and stereo audio applications
• Low quiescent current consumption for battery-powered efficiency
• Integrated pop-noise suppression circuitry to prevent speaker transients
• Differential input configuration for improved noise immunity

Applications

• Portable digital audio players
• Mobile phone speaker amplification
• Personal computer multimedia systems
• Low-voltage consumer electronics

Procurement Notes

Verify the specific ordering suffix TE1 against the manufacturer's latest documentation to confirm packaging details such as reel quantity and tape specifications. Confirm RoHS compliance status as historical data indicates variations between standard and -TE3/TE1 variants. Ensure the procurement source provides valid traceability for this discontinued series.

Selection Notes

Select this component for designs requiring a compact dual amplifier with minimal external components. The 8-DMP package suits space-constrained PCB layouts. Verify that the system supply voltage remains within the 1.8 V to 4.5 V range to ensure proper operation and avoid exceeding absolute maximum ratings.

Part Context

The NJM2076 belongs to a family of low-voltage audio amplifiers designed for portable devices. It serves as a cost-effective solution for driving small speakers in battery-operated equipment. The device integrates protection features and requires few external parts, simplifying the design process for manufacturers of mobile audio gear.

Replacement Considerations

Check for direct pin-compatible substitutes within the NJM2076 series, such as the NJM2076M or NJM2076M-T1, noting differences in packaging format. Evaluate alternative dual Class-AB amplifiers from other manufacturers if the NJM2076 series is fully obsolete.
