The ADUM1201ARZ-RL7 is a digital isolator manufactured by Analog Devices Inc. The device adopts iCoupler® technology, which can realize high-speed and high-precision isolation, effectively isolate signal and power, and improve the reliability and safety of the circuit
The ADUM1201ARZ-RL7 adopts a highly integrated monolithic design with two built-in iCoupler isolation channels for bidirectional data transmission and power isolation. The device provides transfer rates up to 100 Mbps, suitable for high-speed data transmission and communication applications. In addition, the device has advantages such as wide operating voltage range, low power consumption, and low electromagnetic radiation, which can help designers realize low-cost, high-performance circuit design
The ADUM1201 isolator provides two independent isolation channels in a variety of channel configurations and data rates. The devices operate from a supply voltage range of 2.7V to 5.5V on either side, providing compatibility with lower voltage systems as well as the voltage translation function of the isolation barrier.
The ADuM1201 provide low pulse width distortion (<3 ns for CR grade) and tight channelto-channel matching (<3 ns for CR grade). Unlike other optocoupler alternatives, the ADuM1200/ADuM1201 isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during powerup/power-down conditions.
The ADuM1201 digital isolator require no external interface circuitry for the logic interfaces. Power supply bypassing is strongly recommended at the input and output supply pins.
The capacitor value must be between 0.01 μF and 0.1 μF.
The total lead length between both ends of the capacitor and the input power supply pin must not exceed 20 mm.
This isolation component combines high-speed CMOS and monolithic transformer technology to provide excellent performance characteristics due to alternatives such as optocouplers. By avoiding the use of LEDs and photodiodes, iCoupler devices eliminate the design difficulties typically associated with optocouplers
Simple iCoupler digital interface and stable performance characteristics eliminate typical optocoupler issues related to uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects
These iCoupler products eliminate the need for external drivers and other discrete components. In addition, iCoupler devices consume only one-tenth to one-sixth the power of optocouplers at similar signal data rates
ADUM1201ARZ-RL7 adopts a highly integrated digital signal processing circuit, which can realize code rate detection and correction, and voltage monitoring and other functions. The device also has built-in over-voltage protection and short-circuit protection circuits to protect the device from damage under abnormal conditions. It comes in a SOIC package for easy mounting and layout
The device is widely used in industrial automation, communication and medical equipment, power management, measurement and control systems and other fields, which can help designers achieve reliability and high performance circuit design. It can also be used in lightning protection and anti-jamming circuit design to improve the anti-jamming and electromagnetic compatibility performance of the circuit
ADUM1201ARZ-RL7 is a high-performance, high-reliability digital isolator, which has the advantages of high speed, low power consumption, and low electromagnetic radiation. It can be applied to a variety of high-demand circuit designs and is an indispensable choice for designers.
