Norwood, Mass.Analog Devices Inc. (ADI) announced what it says are the industry's smallest four-channel digital isolators.
Housed in a small, 5 mm - 6 mm, QSOP (quarter-size small outline package), the ADuM744x digital isolators can isolate four channels of data and power, while reducing board space up to 70 percent and cutting costs by 20 percent, according to ADI. This is especially effective for those applications that need only up to a 1-kV rms isolation rating and for cost-sensitive designs for which small size is more critical than isolation requirements.
The ADuM744x family of iCoupler digital isolators, comprised of the ADuM7440, ADuM7441, and ADuM7442, is available in a variety of configurations with multiple channel-direction options and data-rate options ranging from 1 Mbps (megabits per second) to 25 Mbps. The devices offer a 3.0-V to 5.5-V supply voltage range, which provides compatibility with lower voltage systems and enables voltage translation across the isolation barrier. The ADuM744x digital isolators offer low power consumption while providing low pulse-width distortion.
Each product also features an input glitch filter to protect against extraneous noise disturbances. Designed specifically for size and cost savings, the ADuM744x offerings are not simply de-rated versions of existing products as are competing 1-kV rms digital isolators.
Pricing: $1.50 each in 1,000-piece quantities.
