Digital isolators are a type of electronic component designed to provide galvanic isolation between two separate circuits. The NMUSB202MC-R7 is a digital isolator that is widely used in a variety of applications. It features two ports, each with 8 differential or single-ended bidirectional logic I/O pins, which are isolated from each other using a capacitively coupled transmitter. This isolator offers a wide range of features and benefits which make it an ideal solution for applications such as automotive, industrial, medical, aerospace and many more.

The NMUSB202MC-R7 utilizes a digital signal conditioner to provide a high level of electrical isolation between two differential or single-ended ports of logic I/O pins. This isolator uses an ESD protection circuit and an on-board regulator to ensure reliable operation in a variety of harsh environments. The on-board capacitively coupled transmitter isolates both the differential and single-ended I/O ports from each other, meaning that the isolation distance between them can be up to 1,000V peak. The device also features low power consumption and minimal standby current.

The principal application fields of the NMUSB202MC-R7 include data acquisition systems, industrial control systems, signal processing systems, automation and switching systems, and embedded systems. As a high-performance digital isolator, it is suitable for a wide range of applications with a high degree of environmental noise or electromagnetic interference (EMI) present. The device is suitable for use in low-noise, safety-critical environments where reliable operation is essential.

The working principle of the NMUSB202MC-R7 is based on capacitively coupled isolation. In this type of device, the I/O ports are interconnected using capacitors, which allow the signals to pass between the ports while providing a high degree of isolation. The device is designed to provide both differential and single-ended isolation, with the differential port providing superior performance over the single-ended port. The on-board capacitively coupled isolation transmitter ensures that the signal from one port does not affect the signal of another port, and also reduces the emissions of RF energy.

The NMUSB202MC-R7 is a reliable and robust digital isolator which can be used in a wide range of demanding applications. Its features and benefits make it ideal for applications with a high level of EMI or environmental noise present. The digital signal conditioning and on-board regulator ensure reliable operation in harsh environments, while the robust ESD protection circuit prevents damage to the device. The use of a capacitively coupled isolator ensures that the ports are securely isolated from each other, providing superior performance over a wide range of temperatures and environments.
