The ADuM41541 is an SPIsolator™digital isolator optimized for a serial peripheral interface (SPI) that includes support for up to four slave devices. Based on the Analog Devices, Inc., iCoupler®chip scale transformer technology, the low propagation delay and jitter in the CLK, MO/SI, MI/SO, and SS SPI bus signals support SPI clock rates of up to 17 MHz.The ADuM4154 isolator also provides a slave select multiplexing system that allows up to four slave devices to be serviced from one isolator. When a target slave is selected, the slave select signal propagates to the desired output with low propagation delay, allowing tight timing control. The isolated SSx is addressed through a 250 kbps low speed, 2-channel address bus, allowing the target slave device to be changed in as little as 2.5 μs.ApplicationsIndustrial programmable logic controllers (PLCs)Sensor isolation

The ADuM4190 is an isolated error amplifier based on ADI,iCoupler®technology. The ADuM4190 is ideal for linear feedback power supplies. The primary side controllers of the ADuM4190 enable improvements in transient response, power density, and stability as compared to commonly used optocoupler and shunt regulator solutions.Unlike optocoupler-based solutions, which have an uncertain current transfer ratio over lifetime and at high temperatures, the ADuM4190 transfer function does not change over its lifetime and is stable over a wide temperature range of −40°C to +125°C.Included in the ADuM4190 is a wideband operational amplifier for a variety of commonly used power supply loop compensation techniques. The ADuM4190 is fast enough to allow a feedback loop to react to fast transient conditions and overcurrent conditions. Also included is a high accuracy 1.225 V reference to compare with the supply output setpoint.The ADuM4190 is packaged in a wide body, 16-lead SOIC package for a reinforced 5 kV rms isolation voltage rating.ApplicationsLinear feedback power suppliesInvertersUninterruptible power supplies (UPS)DOSA-compatible modulesVoltage monitors
