MAX14948EWE+T

Digital Isolators are used to provide electrical isolation between systems while allowing data to be transferred between them. The MAX14948EWE+T is an integrated digital isolator with an integrated transformer designed to provide isolation between two systems. The device features a low-voltage differential signaling (LVDS) interface with data rates up to 1 Mbps. It operates from a single +3.3V power supply and supports an operating temperature range of -40°C to +85°C.

The MAX14948EWE+T is available in a small 5-lead SOT-23 package which is designed to minimize the size and cost of the isolator while still providing reliable electrical isolation. The device is capable of providing data isolation between two systems up to 1250 VDC. It can also provide up to 100 ns of glitch-free data transfer, making it suitable for a variety of applications where data needs to be transferred reliably between two systems with different electrical characteristics.

The operating principle of the MAX14948EWE+T is based on a concept called capacitively coupled galvanic isolation. This method involves using capacitors to couple electrical signals between two systems while providing adequate electrical insulation. The MAX14948EWE+T utilizes a transformer instead of capacitors to provide higher isolation levels and faster transmission speeds, while still allowing data to be transferred between two systems.

The MAX14948EWE+T is most often used in applications where high levels of data isolation are needed and where space constraints are important. Examples of common applications include data communication across mixed voltage levels, handshaking and control signaling, and isolation of microcontrollers and other sensitive electronics. The device can also be used to isolate sensors for medical, industrial, and automotive applications.

In summary, the MAX14948EWE+T is a small, low-cost digital isolator designed to provide electrical isolation and data transfer between two systems in a variety of applications. The device utilizes an integrated transformer to achieve high levels of isolation and fast data transmission speeds while still allowing for reliable data transfer between two systems.
