Digital isolators are electronic components designed to electrically separate two electronic circuits while providing a highly reliable data path for communications and isolation of sensitive nodes. The ADUM2402CRIZ is a popular digital isolator offering bi-directional isolation with the latest CMOS technology using CMOS-programmable technology to create a low-profile and open-drain IC compatible with standard designs.

Features of the ADUM2402CRIZ

The ADUM2402CRIZ is an optocoupler featuring both bi-directional data transmission and voltage protection. It has an isolation rating of up to 600V RMS, a switching speed of 5 ns, and an isolation distance of 250V. The switching speed and isolation distance make the ADUM2402CRIZ an ideal digital isolation component when high-speed data transfer is required.

Application field of the ADUM2402CRIZ

The ADUM2402CRIZ is used in a variety of applications including industrial automation, motor control, data acquisition and measurement, process control, and isolation amplifiers. It is widely used in the field of power electronics as it provides superior protection against electrical noise and provides high-speed switching capabilities. Additionally, the ADUM2402CRIZ is compatible with various communication protocols such as CANBus, RS-485, I2C, and SPI.

Working principle of the ADUM2402CRIZ

The ADUM2402CRIZ works by using an LED to create an optical signal and a photo diode to detect the optical signal on the other side. The LED and the photo diode are connected to isolated circuitry that creates the electrical isolation, while the data passes between the isolated circuits through the LED. The data is passed from one isolated circuit to the other through high speed pulse width modulation, which creates a digital signal on the output side of the ADUM2402CRIZ.

The ADUM2402CRIZ is an efficient device because it uses an optical signal to transfer data instead of an electrical signal. This eliminates the risk of electrical noise which can interfere with the data transfer. Additionally, because the optical signal is self-contained, the transfer between the two isolated circuits is very low power, making it an ideal choice for low power designs.

Conclusion

The ADUM2402CRIZ is a digital isolator used to electrically separate two electronic circuits while providing a fast and reliable data transmission between them. It has excellent isolation ratings, a fast switching speed, and can be used in various applications. Additionally, because it uses an optical signal to transfer data, it eliminates the risk of electrical noise which can interfere with data transmission.
