NJU72750AV-TE1

Overview

The NJU72750AV-TE1 is a stereo analog switch IC manufactured by Nisshinbo Micro Devices, designed for high-performance audio signal routing. It features a dual configuration of two 3-pole 7-throw (3P7T) switches, providing a total of seven inputs and three outputs per channel. The device operates with a single supply voltage ranging from 9 V to 15 V or a dual supply from ±4.5 V to ±7.5 V. It incorporates a 2-wired serial bus control interface for managing switching states. The maximum on-resistance is specified at 40 Ohms and 1 kOhms under different conditions. The component supports surface mount installation in an SSOP32 package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Dual 3P7T analog switch architecture enabling complex multi-source audio routing
• Controlled via a 2-wired serial bus interface for simplified system integration
• Supports both single-supply and dual-supply power configurations for flexible design
• Low on-resistance characteristics suitable for high-fidelity audio signal paths

Applications

• Multi-zone audio distribution systems requiring source selection
• Professional audio mixing consoles and signal routing matrices
• Home theater receivers and surround sound processors
• Audio testing equipment and measurement instruments

Procurement Notes

Verify the specific suffix TE1 indicates the reel packaging format when ordering. Confirm that the SSOP32 package dimensions align with the target PCB footprint. Ensure the design accommodates the required 9V to 15V single supply or ±4.5V to ±7.5V dual supply rails. Check humidity sensitivity handling requirements during storage and assembly processes.

Selection Notes

Select this component when a high-channel-count analog switch is required for stereo audio applications. The 2-wired serial interface reduces pin count compared to parallel control schemes. Consider the on-resistance specifications relative to the source impedance to maintain signal integrity. Evaluate the thermal performance within the specified operating temperature range for the intended environment.

Part Context

This part belongs to the NJU72 series of audio switches from Nisshinbo Micro Devices. It is functionally similar to the NJU72751A but offers a different input/output topology. The series is characterized by low distortion and noise, targeting high-end audio equipment. The AV designation typically refers to the specific tape and reel packaging variant.

Replacement Considerations

The NJU72751A serves as a related alternative within the same product family, offering a 4-input 4-output configuration instead of 7-input 3-output. Verify pin compatibility and control logic differences before substitution. Other series components may require significant circuit redesign due to interface or voltage differences.
