Shenzhen Meiyuxin Technology Co., Ltd. [ADI Chip Agent] Supplies New Original ADUM1201ARZ-RL7 Digital Isolator! ! !

DESCRIPTION

ADUM1201ARZ-RL7 are dual-channel digital isolators based on the Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic transformer technologies, these isolation components provide outstanding performance characteristics superior to alternatives, such as optocouplers.

ADUM1201ARZ-RL7 By avoiding the use of LEDs and photodiodes, iCoupler devices remove the design difficulties commonly associated with optocouplers.

ADUM1201ARZ-RL7 The typical optocoupler concerns regarding uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects are eliminated with the simple iCoupler digital interfaces and stable performance characteristics. The need for external drivers and other discrete components is eliminated with these iCoupler products. Furthermore, iCoupler devices consume one-tenth to one-sixth the power of optocouplers at comparable signal data rates.

ADUM1201ARZ-RL7 isolators provide two independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide). Both devices operate with the supply voltage on either side ranging from 2.7 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling a voltage translation functionality across the isolation barrier. In addition, the ADuM1200/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 ADUM1201ARZ-RL7 isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during powerup/power-down conditions.

ADUM1201ARZ-RL7 are automotive grade  versions qualified for 125°C operation. See the Automotive Products section for more information.
