AD260BND-1 Digital Isolators: Pinout, Specification, Datasheet

The AD260BND-1 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 optoisolators 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.

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/µs without false triggering or damage to the device.
