ADuM230E Triple-Channel Digital Isolators

Analog Devices ADuM230E Triple-Channel Digital Isolators are based on iCoupler® technology and offer performance characteristics superior to alternatives including optocoupler devices and other integrated couplers. ADuM230E isolators ensure dc correctness in the absence of input logic transitions. Designers can choose from two different fail-safe options that allow the outputs to transition to a predetermined state when the input power supply is not applied or the inputs are disabled. ADuM230E isolators provide a maximum propagation delay of 13ns with a pulse width distortion of less than 3ns at 5V operation. The data channels are independent and are available in a variety of configurations with a withstand voltage rating of 5.0kVrms. Channel matching is tight at 3.0ns maximum. The ADuM230E isolators operate with the supply voltage on either side ranging from 1.8V to 5V, allowing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier.

Analog Devices Robust iCoupler Digital Isolators

Analog Devices Robust iCoupler® Digital Isolators ensure safe system performance for applications operating in noisy, harsh, and unpredictable environments. These iCoupler isolators feature high-speed CMOS and monolithic air core transformer technology and an on-off-keying (OOK) architecture. The isolators offer outstanding performance and proven galvanic isolation. To protect data signals, these iCoupler digital isolators provide the industry's highest surge protection of 16kVpk and withstand voltage ratings up to 5kVrms. For additional surge protection, the isolators have a 10KV reinforced surge rating. To support high-speed communications and data integrity, the isolators have 150Mbps throughput, 14ns max. propagation delay, and 100kV/µs transient immunity. Suitable for a wide variety of applications, the isolators operate over a 1.7V to 5.5V supply range and feature 1 to 4 input channels.
