Analog Devices claims that it is offering the industry’s smallest four-channel digital isolators. Housed in a 5-mm x 6-mm, QSOP, the ADuM744x digital isolators can isolate four channels of data and power, while reducing board space up to 70% and cutting costs by 20%. This is especially effective for those applications that need only up to a 1-k Vrms isolation rating and for cost-sensitive designs for which small size is more critical than isolation requirements. The ADuM744x family of digital isolators comprises the ADuM7440, ADuM7441, and ADuM7442. They are available in a variety of configurations with multiple channel-direction options and data-rate options ranging from 1 to 25 Mbits/s. The devices offer a 3.0- to 5.5-V supply voltage range, which provides compatibility with lower voltage systems and enables voltage translation across the isolation barrier. They consume very little power while providing low pulse-width distortion. Each product also features an input glitch filter to protect against extraneous noise disturbances. The ADuM744x family of digital isolators is sampling now. Pricing is set at $1.50 each in 1000-piece quantities. ANALOG DEVICES INC., Norwood, MA. (781) 329-4700.
