NJM2073M-TE1

Overview

The NJM2073M-TE1 is a dual low voltage power amplifier in an 8-DMP package. It operates on a supply voltage of 1.8V to 15V with a typical operating current of 6mA. In BTL configuration at 6V, it delivers 800mW into 16Ω. In stereo mode at 6V, each channel provides 270mW into 8Ω. The device features a closed-loop voltage gain of 44dB and total harmonic distortion of 0.2%.

Feature Summary

• Supports bridge-tied load (BTL) or stereo configurations for flexible audio output topologies.
• Eliminates turn-on noise during power-up sequences.
• Utilizes bipolar technology to achieve low crossover distortion.
• Maintains low operating current suitable for portable battery-powered applications.

Applications

• Dual audio power amplification in portable radios
• Audio output stages in handy cassette players

Procurement Notes

Verify the specific ordering suffix TE1 against the manufacturer's latest documentation to confirm tape-and-reel packaging specifications. Ensure the component matches the DMP-8 package outline dimensions provided in the datasheet. Confirm RoHS compliance status through official Nisshinbo Micro Devices channels prior to final procurement decisions.

Selection Notes

Select this component when designing circuits requiring dual-channel amplification within a single integrated circuit footprint. It is appropriate for systems needing operation from low supply voltages down to 1.8V. Consider the thermal dissipation limits of the DMP-8 package when determining heat sinking requirements for high-power outputs.

Part Context

This part belongs to the NJM2073 series of dual low voltage power amplifiers manufactured by Nisshinbo Micro Devices Inc. The series is designed specifically for portable audio equipment where space and power efficiency are critical constraints. The M-type designation indicates the surface-mount DMP-8 package variant.

Replacement Considerations

Consult official manufacturer substitution lists for verified alternatives. Generic cross-references may not match the specific electrical characteristics or pinout configurations required for direct replacement in existing designs.

FAQ

How does the NJM2073 handle parasitic oscillation?

The datasheet recommends placing a parallel resistor and capacitor network across the speaker load to prevent parasitic oscillation. Additionally, capacitors should be placed near the ground and supply voltage pins.

What is the function of the mute circuit?

When the mute function is activated, the output level saturates to the GND side, effectively silencing the audio output.
