The ADuM41501is a 6-channel, SPIsolator™digital isolator optimized for isolated serial peripheral interfaces (SPIs). Based on the Analog Devices, Inc., iCoupler®chip scale transformer technology, the low propagation delay in the CLK, MO/SI, MI/SO, andSSSPI bus signals supports SPI clock rates of up to 17 MHz. These channels operate with 13 ns propagation delay and 1 ns jitter to optimize timing for SPI.The ADuM4150 isolator also provides two additional independent low data rate isolation channels, one channel in each direction. Data in the slow channels is sampled and serialized for a 250 kbps data rate with 2.5 μs of jitter.The ADuM4150 supports a delay clock output on the primary side of the device. This output can be used with an additional clocked port on the primary to support 40 MHz clock performance. See the Delay Clock section for more information.Analog Devices is in the process of updating documentation to provide terminology and language that is culturally appropriate. This is a process with a wide scope and will be phased in as quickly as possible. Thank you for your patience.ApplicationsIndustrial programmable logic controllers (PLC)Sensor isolation

The ADuM4160 is a USB port isolator, based on Analog Devices, Inc.,iCoupler®technology. Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics and are easily integrated with low and full speed USB-compatible peripheral devices.Many microcontrollers implement USB so that it presents only the D+ and D− lines to external pins. This is desirable in many cases because it minimizes external components and simplifies the design; however, this presents particular challenges when isolation is required. USB lines must automatically switch between actively driving D+/D−, receiving data, and allowing external resistors to set the idle state of the bus. The ADuM4160 provides mechanisms for detecting the direction of data flow and control over the state of the output buffers. Data direction is determined on a packet-by-packet basis.The ADuM4160 uses the edge detection basediCoupler technology in conjunction with internal logic to implement a transparent, easily configured, upstream facing port isolator. Isolating an upstream facing port provides several advantages in simplicity, power management, and robust operation.The isolator has propagation delay comparable to that of a standard hub and cable. It operates with the supply voltage on either side ranging from 3.1 V to 5.5 V, allowing connection directly to VBUSby internally regulating the voltage to the signaling level. The ADuM4160 provides isolated control of the pull-up resistor to allow the peripheral to control connection timing. The device has a low idle current; a suspend mode is not required.APPLICATIONSUSB peripheral isolationIsolated USB hubMedical applications
