Overview
The NJU72750AV-TE1 is a dual analog switch IC featuring a 7-input to 3-output matrix configuration for each of its two independent channels. It operates on a dual power supply ranging from ±4.5V to ±7.5V or a single supply from +9.0V to +15.0V. The device utilizes a 2-wired serial bus for control, allowing selectable chip addressing to support up to four units on the same bus line. Key electrical parameters include a typical ON resistance of 15Ω and a total harmonic distortion of 0.0004%. It is housed in an SSOP32 package.
Feature Summary
- Dual-channel architecture with independent A and B channel switching capabilities
- Controlled via a 2-wired serial bus interface with selectable chip addressing
- Low distortion performance suitable for high-fidelity audio applications
- Integrated low-impedance output switches for signal buffering
Applications
- Multi-channel audio systems
- AV amplifiers
- DVD receivers
Procurement Notes
Verify the component against official Nisshinbo Micro Devices documentation to confirm pinout compatibility and electrical specifications. Ensure that the operating voltage range matches the system requirements, as the device supports both dual and single supply configurations. Check for moisture sensitivity handling during storage and assembly processes.
Selection Notes
Select this component when designing multi-channel audio routing matrices requiring low distortion and independent channel control. Consider the SSOP32 package dimensions and the need for external decoupling capacitors as shown in application circuits. Verify that the serial bus logic levels are compatible with the controlling microcontroller or processor.
Part Context
This part belongs to the NJU72 series of analog switches manufactured by Nisshinbo Micro Devices. It is specifically designed for consumer audio applications where multiple input sources need to be routed to various outputs. The series includes similar devices like the NJU72751A, which offers a different input/output configuration.
Replacement Considerations
The NJU72751A is a related device within the same family, offering a 4-input to 4-output configuration instead of 7-to-3. Both share similar control interfaces and electrical characteristics but differ in pin count usage and switching matrix size.
