The AD260 is designed using Analog Devices new IsoLogic circuit architecture to isolate five digital control signals to/ from a micro controller 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. The isolation barrier of the AD260 B Grade is 100% tested at 3.5 kV rms (system to field). The barrier design also provides excellent common-mode transient immunity from 10 kV/us common-mode voltage excursions of field side terminals relative to the system side, with no false output triggering on either side. Each output is updated within nanoseconds by input logic transitions, the AD260 also has a continuous output update feature that automatically updates each output based on the dc level of the input. This guarantees the output is always valid 10 us after a fault condition or after the power-up reset interval. The AD260 also has an integral center tap transformer for generating isolated power. Typically driven by a 5 V push-pull drive at the primary, it will generate a 37 V p-p output capable of supplying up to 1.5 W. This can then be regulated to the desired voltage, including - 5 V dc for circuit components and 24 V for a 20 mA loop supply when needed. PRODUCT Highlights Six Isolated Logic Line I/O Configurations Available : The AD260 is available in six pin-compatible versions of I/O configurations to meet a wide variety of requirements. Wide Bandwidth with Minimal Edge Error: The AD260 with IsoLogic affords extremely fast isolation of logic signals due to its 20 MHz bandwidth and 14 ns propagation delay. It maintains a waveform input-to-output edge transition error of typically less than -1 ns (total) for positive vs. negative transition. 3.5 kV rms Test Voltage Isolation Rating: The AD260 B Grade is rated to operate at 1.25 kV rms and is 100% production tested at 3.5 kV rms, using a standard ADI test method. High Transient Immunity: The AD260 rejects common mode transients slewing at up to 10 kV/us without false triggering or damage to the device.
