Digital Isolators are one of the most popular ways of transmitting and receiving signals over long distances with minimal power loss. They are used in a variety of applications including medical equipment, industrial equipment, and civilian navigation. They are also useful in isolating specific parts of an signal from the rest, for example, a thermal signal from other instrumentation signals. Many designs exist, but the MAX14936FAWE+T is one of the most popular.

The MAX14936FAWE+T contains two galvanic isolators connected in parallel, each with a maximum isolation voltage of 5kV. These are protected by a surge current buffer and a transient voltage clamping detector. These components allow the isolators to isolate high speed data up to 2Mbps and analogue signals up to 1MHz. The device is available in both single and dual channel configurations.

The MAX14936FAWE+T also features a Wide Common Mode Range (CMR) transient survival for analog signals. This extends the common mode voltage range, which helps to prevent signal distortion caused by transient noise. In addition, the device includes on-chip OVP protection and ESD protection, for both current and voltage signals.

The MAX14936FAWE+T has a broad range of applications. It can be used to safely transfer analogue or digital data between two points that are electrically isolated from one another. It can also be used for monitoring and controlling industrial machinery, as well as providing input and output logic signals. The device is also used in medical applications, such as monitoring patient vital signs, since it has very high level of accuracy and reliability.

The main principle of operation of the MAX14936FAWE+T is based on magnetics. An external low power supply is used to generate magnetic field across the isolator’s active components. This creates an electrical potential across the electrostatic barrier layer, which provides electrical isolation between the input and output signals. The isolator also amplifies or reproduces the low voltage input signal and produces the high voltage output signal.

Moreover, the unique surge current buffer feature of the MAX14936FAWE+T helps provide a high degree of immunity to noise transients and power supply voltage fluctuations. This is done by clamping the potential power surges below the defined safe working limits and preventing them from reaching the output side of the device.

The MAX14936FAWE+T digital isolator is a robust and efficient device, designed for high speed digital and analogue signal transmission. It has a plethora of features that make it suitable for a wide range of applications, offering reliable signal isolation and protection from noise transients and power supply voltage fluctuations.
