Digital Isolators provide a reliable way to transfer digital signals with electrical isolation between two circuits in an effective and secure manner. The ADUM131E0BRZ is an application-specific digital isolator designed to minimize communication errors due to common-mode and transient voltage differences. It utilizes an integral analog-to-digital/digital-to-analog (AD/DA) converter that performs the signal conditioning.

The ADUM131E0BRZ digital isolator has a dual channel construction consisting of a digital receiving channel (RX) and a digital transmitting channel (TX). The RX channel of the ADUM131E0BRZ contains a receive side integrated transformer, a comparator, and a differential receiver. The RX channel is also integrated with a transimpedance amplifier that amplifies the received signal to a predetermined voltage threshold. The comparator then compares the amplified signal with a reference voltage and converts it into a logic signal. This logic signal is then transmitted to the TX channel.

The TX channel of the ADUM131E0BRZ contains a digital to analog converter (DAC) that is integrated with the comparator. The DAC converts the logic signal received from the RX channel into an analog voltage. This analog voltage is then inverted and sent to the secondary side of the isolated transformers. The analogous signal is then transmitted across the primary side of the isolated transformers and is received by the comparator of the RX channel. The comparator then generates a logic signal that is sent to the receiver side of the integrated transformer and is sent to the digital end.

The ADUM131E0BRZ digital isolator is designed to minimize communication errors due to common-mode and transient voltage differences and achieve communication safety and isolation. It has a wide range of applications with continuous power optimization, such as high-frequency isolation and power conversion systems, industrial control systems, medical instrumentation systems, robotics, data acquisition systems, and automotive electronics.

The working principle of the ADUM131E0BRZ digital isolator is simple. When the logic signal is transmitted from the TX channel to the RX channel, it is converted to an analog voltage. This analog voltage is then inverted and sent to the secondary side of the isolated transformers. The analogous signal is then transmitted across the primary side of the isolated transformers and is received by the comparator of the RX channel. The comparator then generates a logic signal which is sent to the receiver side of the integrated transformer and is sent to the digital end.

The ADUM131E0BRZ digital isolator provides reliable signal transfer in a wide range of applications while ensuring communication safety and isolation. It is designed to minimize communication errors due to common-mode and transient voltage differences. The working principle of the digital isolator is simple, yet very effective and reliable, making it a very popular choice for application-specific digital isolation technology.
