NJW1151M

Audio Special Purpose Overview

The NJW1151M is a 6-channel electronic volume IC manufactured by Nisshinbo Micro Devices Inc. It integrates master volume, balance control for L/R channels, trim level control for C/SL/SR/SW channels, and independent tone control (Bass/Treble) for L/R channels. The device operates on a single supply voltage of +8.0V to +15.0V with a typical supply current of 10mA at 25°C. It utilizes an I2C bus interface for internal status control. Key electrical parameters include a maximum attenuation of -79dB for the master volume, -30dB for balance, and -20dB for trim levels. The output noise is typically -110dBV (A-weighted), and total harmonic distortion is 0.005% at 1kHz.

Audio Special Purpose Applications

• AV amplifiers
• Mini stereo components
• Speaker systems

Audio Special Purpose Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity upon receipt, as the unit is supplied in tubes. Check RoHS compliance documentation if required for specific regulatory standards. Note that this component may be subject to end-of-life status; verify current availability and lead times with suppliers before finalizing design-in decisions.

Audio Special Purpose Selection Notes

Select the NJW1151M when a multi-channel audio system requires integrated volume, balance, and tone controls managed via a digital interface. Ensure the power supply voltage falls within the +8.0V to +15.0V range. Verify that the application supports I2C communication protocols. Consider the SDMP30 package dimensions for PCB layout constraints. This component is suitable for applications requiring independent channel trimming and mute functions.

Audio Special Purpose Part Context

The NJW1151 belongs to the NJW115x series of electronic volume controllers from Nisshinbo Micro Devices. It is part of a lineup designed for consumer audio applications, offering Bi-CMOS technology for performance. Related parts in the series may offer different channel counts or interface options, but the NJW1151 specifically provides 6 channels with comprehensive tone and balance adjustments controlled via I2C.
