The ADuM3480/ADuM3481/ADuM3482 are quad-channel digital isolators based on the Analog Devices, Inc.,iCoupler® technology. Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as optocoupler devices and other integrated couplers. With typical propagation delay reduced to 25 ns, pulse width distortion is also halved.
The four channels of the ADuM3480/ADuM3481/ADuM3482 are available in a variety of channel configurations with two data rate grades up to 25 Mbps (see the Ordering Guide section). All models use separate core and I/O power supplies. The core operates between 3.0 V and 5.5 V, whereas the I/O supply can range from 1.8 V to 5.5 V. If operation is required within the range of the core supply, the two supplies can be tied together to allow single-supply operation. When the I/O must interface with logic levels that are different from the core supply voltage, then the I/O supply can be operated independently of the core supply over a wider range. The minimum I/O supply voltage is 1.8 V, allowing compatibility with low voltage logic. Both core and I/O supplies are required for proper operation.
Applications
- General-purpose multichannel isolation
- SPI interface/data converter isolation
- Industrial field bus isolation
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
