Digital Isolators: ADUM2280CRIZ-RL Application Field and Working PrincipleThe ADUM2280CRIZ-RL is a digital isolator chip, and it is the latest addition to the Analogue Device’s well-established iCoupler® brand of digital isolators. It has been designed to operate in demanding harsh industrial, medical, and automotive applications where system isolation and fault tolerance are required. This chip is used as an alternative to othe traditional methods like opto-couplers, transformers, and other discrete components used to provide electrical isolation.The ADUM2280CRIZ-RL is a 3-channel digital isolator and it features very low power consumption for improved efficiency. It also offers superior temperature stability, noise immunity and ESD protection. It is good for applications where power supplies are known to fluctuate widely. With its rated working voltage of up to 33V, it can be used in a wide range of applications in highly-demanding environments. This chip is made of a hybridized packaging technology called ‘isolator-in-package’, which combines both an analog input stage and a digital output stage into a single device for improved spacing, noise immunity and superior temperature stability. This also allows for a very compact integration, occupying minimal space in the target application. In order to operate, the ADUM2280CRIZ-RL requires two separate power supplies; one for the input side and one for the output side. The input side power supply is used to power the analog portion of the device, as the digital output side power supply is used exclusively for activating the output depending on the input. The power supplies should be at least 5 V, and not more than 33 V to avoid damaging the chip.The dual power supply system helps to reduce power consumption by only activating the digital output stage when it receives a signal or an activation command. The power supply to the input stage is always present even when there isn’t any signal. The application field is wide. The ADUM2260CRIZ-RL is a reliable and robust isolator for any application requiring both electrical isolation and intermediate signal conditioning. It is well suited for use in medical and automotive applications; HF wave generators; and other applications involving transient voltage signals, noisy signals, high voltage, and high temperature environments. In conclusion, the ADUM2280CRIZ-RL is an excellent chip for providing electrical isolation for data transmission and intermediate signal conditioning. With very low power consumption and excellent temperature stability, it can perform reliably in a wide range of demanding applications.
