ADM3055E主要特性:

ADI公司的ADM3055E是集成了隔离DC/DC转换器的5kVrms隔离的CAN物理层收发器,满足CAN灵活数据(FD)速率要求,可以工作高达5Mbps或更高,并和ISO 11898-2标准兼容.器件采用ADI的iCoupler®技术,把三路隔离器,CAN收发器和ADI isoPower® DC/DC转换器集成在SOIC表面安装封装中,工作电压5V,工作温度−40℃到 +105℃,主要用在CANOpen,DeviceNet和其它CAN总线应用,工业自动化,过程控制和建筑物控制以及交通运输和基础设备.本文介绍了ADM3055E主要特性和功能框图,以及评估板EVAL-ADM3055EEBZ主要特性,电路图,材料清单和PCB设计图.
Industrial temperature range: −40℃to +105℃
Dominant timeout functionality protects against bus lock up in a fault condition. The current limiting and thermal shutdown features protect against output short circuits. The device is fully specified over an industrial temperature range of −40℃to +105℃.
Extended common-mode range: ±25 V

5 kV rms signal and power isolated CAN transceiver
Safety and regulatory approvals
Passes EN 55022 Class B by 6 dB
The device employs Analog Devices, Inc., iCoupler® technology to combine a 3-channel isolator, a CAN transceiver, and Analog Devices isoPower® dc-to-dc converter into a single, small outline integrated circuit (SOIC), surface-mount package. The device is powered by a single 5 V supply realizing a fully isolated soluTIon for CAN and CAN FD applicaTIons. Radiated emissions from the high frequency switching of the dc-to-dc convertor are kept below EN 55022 Class B limits by conTInuous adjustments to the switching frequency.

 详解ADI公司的ADM3055E产品


The EVAL-ADM3055EEBZ allows the user to evaluate the ADM3055E isolated signal and power transceiver for controller area network (CAN) or CAN with flexible data rate (CAN FD) networks. The EVAL-ADM3055EEBZ allows all of the input and output functions to work without the need for external components. Based on the Analog Devices, Inc., iCoupler® technology, the ADM3055E integrates logic side on-off keying (OOK) signal isolation channels and an Analog Devices isoPower® dc-to-dc converter to provide regulated, isolated power that is well below CISPR22/EN55022 Class B limits when transmitting on a 2-layer printed circuit board (PCB) with ferrites. The EVAL-ADM3055EEBZ comes populated with an ADM3055E. Full specifications of the ADM3055E can be found in the ADM3055E data sheet, available from Analog Devices, Inc., and must be consulted in conjunction with this user guide when using the EVAL-ADM3055EEBZ.
