ADUM1510

5通道，单向数字隔离器 5-Channel, Unidirectional Digital Isolator

Product Details

The ADuM1510 is a unidirectional, 5-channel isolator based on the Analog Devices, Inc., _i_Coupler® technology. Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as optocoupler devices.

By avoiding the use of LEDs and photodiodes, _i_Coupler devices eliminate the design difficulties commonly associated with optocouplers. The typical optocoupler concerns regarding uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects are eliminated with the simple _i_Coupler digital interfaces and stable performance characteristics. The need for external drivers and other discrete components is eliminated with _i_Coupler products. In addition, _i_Coupler devices run at one-tenth to one-sixth the power consumption of optocouplers at comparable signal data rates.

The ADuM1510 isolator provides five independent isolation channels supporting data rates up to 10 Mbps. The ADuM1510 operates with the supply voltage of either side ranging from 4.5 V to 5.5 V. Unlike other optocoupler alternatives, the ADuM1510 isolator has a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during power-up/ power-down conditions.
