Digital isolators are used to electrically isolate two channels in an electronic system. They provide a safe and effective way to transfer signals between two subsystems. The ADUM251N1BRIZ-RL is a digital isolator that is ideal for applications that require precise transfer of signals between subsystems. This isolator is designed to provide a high level of dynamic performance and low power consumption while maintaining the required isolation.

The ADUM251N1BRIZ-RL is a CMOS type digital isolator with an isolation voltage rating of 7.5 kV. It is designed to comply with the H-series of performance standards, providing increased dielectric strength and insulation level. The isolator is also rated for up to 25 ps integrity of data with a 250 Mbps data rate. The isolator has a maximum supply voltage of 5.5V and a maximum operating current of 50 mA at 25°C.

The ADUM251N1BRIZ-RL is highly efficient in many applications. It is commonly used in audio-visual equipment, instrumentation systems, medical devices, motor control, and process control applications. In addition, it can be used to provide a reliable interface between microcontrollers, logic gates, and DSP components.

The working principle of the ADUM251N1BRIZ-RL digital isolator is based on capacitive-coupling technology. This technology uses two capacitors to transfer the signals between the two channels in an electronic system. A transmitting capacitor is connected to the input side of the isolator and a receiving capacitor is connected to the output side. When a signal is applied to the input side of the isolator, it creates a small electrical charge on the transmitting capacitor, which is then transferred across the two capacitors to the receiving capacitor. This creates a voltage on the receiving capacitor, which is then passed to the output side of the isolator.

The isolation voltage rating of the ADUM251N1BRIZ-RL isolator is 7.5 kV, which is suitable for many applications. The isolator also features a low power consumption and the capability to transmit up to 25 ps integrity of data with a 250 Mbps data rate. It is also designed to provide a surge endurance of 25 V/μs.

In summary, the ADUM251N1BRIZ-RL is a cost-effective digital isolator solution that provides reliable signal transfer between two subsystems. It is designed to have a high level of dynamic performance and low power consumption while maintaining the required isolation. The isolator is suitable for many application fields, including audio-visual equipment, instrumentation systems, medical devices, motor control, and process control. It works by using a capacitive-coupling technology that enables signal transfer between two channels without any direct electrical connection. With its 7.5 KV isolation voltage rating, 25V/μs surge endurance capability, and low power consumption, the ADUM251N1BRIZ-RL is an ideal digital isolator solution for many applications.
