NJM2073D

Overview

The NJM2073D is a dual low voltage power amplifier IC in an 8-lead DIP package. It operates on a supply voltage of 1.8V to 15V with a typical operating current of 6mA. In BTL configuration at 9V, it delivers 2W output power into a 16Ω load. The device features a closed-loop voltage gain of 44dB and a total harmonic distortion of 0.2%. It supports stereo or bridge-tied load configurations.

Feature Summary

Supports both bridge-tied load (BTL) and stereo configurations for flexible audio applications.
Designed for portable devices with low crossover distortion and no turn-on noise.
Utilizes bipolar technology for reliable performance across a wide operating temperature range.

Applications

Dual audio power amplifiers in portable radios
Audio amplification in handy cassette players

Procurement Notes

Verify the specific package type against the datasheet, as the NJM2073 series includes both D-type (DIP8) and M-type (DMP8) packages. Confirm that the required electrical characteristics match the D-Type specifications provided in the official documentation. Ensure compatibility with the intended supply voltage range and load impedance requirements before integration.

Selection Notes

Select this component when a dual-channel amplifier is needed for portable battery-powered equipment. It is suitable for designs requiring operation from 1.8V up to 15V. Consider the BTL capability for higher power output into high-impedance loads or stereo mode for lower impedance speakers. Verify thermal dissipation capabilities within the DIP8 package constraints.

Part Context

The NJM2073 is part of Nisshinbo Micro Devices' dual low voltage power amplifier family. It is designed specifically for portable audio applications where low power consumption and wide voltage operation are critical. The D suffix indicates the Dual Inline Package (DIP8) variant, distinct from the surface mount M-type version.

Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio if availability is an issue. Ensure any substitute maintains the 1.8V to 15V operating voltage range and similar power output characteristics for the target load impedance.
