NJW1151M#

Audio Special Purpose Overview

The NJW1151M# is a 6-channel electronic volume IC manufactured by Nisshinbo Micro Devices Inc. It integrates tone control, balance adjustment, and trim level control for multi-channel audio systems. The device operates on a single supply voltage ranging from +8.0V to +15.0V with a typical supply current of 10mA at 25°C. It features an I2C bus interface for controlling all internal status and variables. Key electrical parameters include a maximum attenuation of -79dB for the master volume, a channel separation of -80dB (A-weighted), and a total harmonic distortion of 0.05% maximum at 1kHz.

Audio Special Purpose Feature Summary

• 6-Channel Master Volume Control: Adjustable from 0dB to -79dB with 1dB steps, including MUTE function.
• Integrated Tone Control: Independent Bass and Treble adjustment (+/-10dB) for Left and Right channels.
• Balance and Trim Functions: L/R balance control (0 to -30dB) and independent trim level control (0 to -20dB) for Center, Surround Left/Right, and Sub Woofer channels.
• I2C Bus Interface: All functions controlled via standard I2C communication protocol.

Audio Special Purpose Applications

• AV Amplifiers
• Mini Stereo Components
• Speaker Systems

Audio Special Purpose Procurement Notes

Verify component availability as the NJW1151M# is listed as End-of-Life (EOL) or discontinued by the manufacturer. Confirm package type (30-SDMP) and interface compatibility before procurement. Check for alternative sources or replacement components if long-term supply is required.

Audio Special Purpose Selection Notes

Select this component for applications requiring integrated 6-channel volume, tone, and balance control in a single IC. Ensure the system power supply is within the +8.0V to +15.0V range. Verify that the microcontroller supports the I2C bus interface for control. Consider the 30-SDMP surface mount package constraints during PCB layout.
