Analog Devices Introduces Digital Isolator With Integrated Transformer Driver And PWM Controller | Digital Isolators | Interface | Press Releases | An.......

Analog Devices, Inc. , a global leader in high performance semiconductors for signal-processing applications, today introduced the industry as first digital isolator with an integrated transformer driver and PWM (pulse-width modulation) controller in a single package. The integration of these components into a small, surface mount 20-lead SSOP (shrink small outline package) enables the new four-channel digital isolator to reduce board space by up to 30 percent and achieve cost reductions of 10 p.......
