AD260 General Description

The AD260 is designed using Analog Devices new IsoLogic circuit architecture to isolate five digital control signals to/ from a microcontroller and its related field I/O components. Six models allow all I/O combinations from five input lines to five output lines, including combinations in between. Every AD260 effectively replaces up to five opto-isolators while also providing the 1.5 W transformer for a 3.5 kV isolated dc-dc power supply circuit.

Each line of the AD260 has a bandwidth of 20 MHz (min) with a propagation delay of only 14 ns, which allows for extremely fast data transmission. Output waveform symmetry is maintained to within ±1 ns of the input so the AD260 can be used to accurately isolate time-based PWM signals.

All field or system output pins of the AD260 can be set to a high resistance three-state level by use of the two enable pins. A field output three-stated offers a convenient method of presetting logic levels at power-up by use of pull-up/down resistors. System side outputs being three-stated allows for easy multiplexing of multiple AD260s.
