Mouser offers ADI digital isolators to protect in harsh environments

Distributor, Mouser Electronics now stock Analog Devices’ ADuM140D/E, quad-channel digital isolators.
 The isolators are based on patented iCoupler digital isolation technology and combine high-speed CMOS and monolithic air core transformer technology for signal reliability, safety, and performance in a package smaller than typical optocouplers, says the company.
 The isolators provide surge protection in harsh, high voltage and high-noise environments. They feature 3.75kVRMS withstand voltage and a low, maximum propagation delay of 13ns, with pulse width distortion less than 3ns. Operating supply voltage on either side ranges from 1.8 to 5V, providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier. Two fail-safe options are offered: the outputs transition to a pre-determined state when the input power supply is not applied, or the inputs are disabled. The devices’ differential architecture is designed for high common-mode transient immunity and high immunity to electrical noise and magnetic interference.
 Operating temperatures is 40 to +125°C. Applications include general-purpose, multi-channel isolation, serial peripheral interface (SPI)/data converter isolation, and industrial fieldbus isolation applications, including those operating in noisy, harsh and unpredictable healthcare and industrial environments.

贸泽电子将供应ADI公司的数字隔离器,以便在恶劣环境下保护器件

分销商,在Mouser Electronics现在库存ADI公司ADuM140D / E,四通道数字隔离器。

隔离器是基于专利的iCoupler数字隔离技术,并集成在比一般小的光电耦合器相结合的高速CMOS和单片空芯变压器技术,信号的可靠性,安全性和性能,表示该公司。

该隔离器提供在恶劣,高电压和高噪声环境下的浪涌保护。它们的特点是3.75kVRMS耐压和13ns低,最大传输延迟,脉冲宽度失真小于3ns的。对任何一方工作电源电压范围为1.8〜5V,提供兼容性与低压系统以及使电压转换功能通过隔离屏障。两个故障安全选项提供:当输入电源没有施加输出过渡到预先确定的状态,或输入被禁止。该器件的差分架构是专为高共模瞬态抑制能力和高抗电噪声和电磁干扰。

工作温度为-40至+ 125°C。应用包括通用,多通道隔离,串行外围接口(SPI)/数据转换器隔离,以及工业现场总线隔离应用,包括那些在嘈杂的,恶劣的和不可预测的医疗和工业环境中进行。
