Digital isolators are a type of integrated circuits that transmit digital signals between circuit domains while providing a high level of electrical isolation. ADUM230E1BRIZ is a digital isolator with an isolation voltage of 2.5 kV rms, designed for both industrial and medical applications. It is ideal for protecting high voltage circuits, as well as providing isolation between circuits that use different ground references, and for transmission of data across circuits that need to be electrically isolated for safety and/or signal integrity reasons.

ADUM230E1BRIZ isolators are capable of converting digital signals to optical signals, and the optical signals back to digital signals, thus providing electrical isolation between input and output. The optical signals are transmitted to and fro via an optical circuit, so that the input and output circuits are electrically isolated. What’s more, since the ADUM230E1BRIZ does not support galvanic isolation, it offers protection against high voltage surges, transients, and EMI/RFI for both data and power lines.

The application field of ADUM230E1BRIZ includes the industrial automation, lighting control, medical equipment, robotics, security systems, and motor control. The working principle of the ADUM230E1BRIZ is based on the opto-coupling technology. It uses an LED as the input source and a photo-transistor as the input detector. The LED is triggered when the input circuit receives the signal, this illuminates the photo-transistor, which generates an amplified signal which is sent to the output circuit via an optical circuit.

The ADUM230E1BRIZ also offers some other beneficial features such as a wide common-mode rejection range, low power consumption, high data rate of up to 1 Mbps, low delay time of 30ns, fast rising and falling edges, and an exceptionally low number of propagation errors. Additionally, the ADUM230E1BRIZ is designed to meet the requirements of the UL, IEC, and CE certified safety standards.

In summary, ADUM230E1BRIZ is a reliable digital isolator that ensures electrical isolation between two circuits. It is perfect for applications where high voltage protection and isolation of data are required, including industrial automation, lighting control, medical equipment, robotics, security systems, and motor control. It provides electrical isolation while still allowing information to be quickly and accurately transmitted across both the input and output circuits.
