Digital Isolators are used to provide electrical isolation between two circuits, which is generally accomplished by using optically insulated components. An example of an isolation device is the AD261AND-5. This device is an integrated step-down DC to DC voltage regulator with input and output terminals that are electrically isolated from each other.

The AD261AND-5 is a digital isolator specifically designed for low voltage applications. It has a wide input voltage range of 18V to 36V and a low output voltage of 5V with 0.1% accuracy. The high efficiency of the device is achieved by using a PWM control scheme coupled with an advanced switching power topology.

The AD261AND-5 is also capable of supplying up to 1.2A of output current with no external components. The device is also protected against input overvoltage and output overcurrent conditions. In most cases, the device can remain in full-on operation up to the point of output overcurrent.

In terms of its working principle, the AD261AND-5 is a DC to DC converter which is designed to provide isolation between input and output. The input is connected to the primary winding of a transformer, while the output is connected to the secondary winding. The input voltage is converted to an appropriate AC voltage level through the transformer, which is then rectified and regulated to provide a steady DC voltagely. The output voltage is also isolated from the input voltage.

The AD261AND-5 is designed to operate over a wide temperature range and offers immunity from electromagnetic interference (EMI). The digital isolator is designed to meet stringent safety compliance standards including IEC61000-6-2, IEC6100-4-2. The device is also capable of providing an ultra-low power shutdown mode, making it suitable for battery powered applications.

In summary, the AD261AND-5 is a low voltage digital isolator designed to provide isolation between input and output. It operates over a wide temperature range and offers resistance to electromagnetic interference. It is also capable of providing an ultra-low power shutdown mode and complying with safety standards.
