ADuM3151 SPIsolator™ Digital Isolators

Featured Product from Mouser Electronics, Inc.

Mouser Electronics, Inc., the global authorized distributor with the newest semiconductors and electronic components, is now stocking the ADuM3151 SPIsolator Digital Isolator from Analog Devices. This new isolator optimizes isolation of serial peripheral interface (SPI) transmissions for higher speeds, while provide additional low speed channels for control and status monitoring functions. The ADuM3151 is based on ADI's award-winning iCoupler® digital isolation technology. This device supports SPI clock rates as high as 17MHz, and provides a slave select multiplexing system that allows up to four slave devices to be serviced from one isolator.

The Analog Devices' ADuM3151 SPIsolator Digital Isolator, available from Mouser Electronics, is a 3.75kV rms, 7-Channel, SPIsolator™ digital isolator that features low propagation delay and low jitter on all multiplexed channels that support SPI clock rates up to 17MHz. The ADuM3151 accommodates up to four slave devices as well as three low data rate isolation channels. Data in the low channels is sampled and serialized for a 250kbps data rate with up to 2.5μs of jitter in the low speed channels.

The ADuM3151 simplifies the design of a complete SPI digital isolation system by using just three components. The high level of functional integration in the ADuM3151 provides developers with a simple solution for isolating high-speed SPI signals along with commonly used low-speed status and control signals in a single package. Faster SPI clock speeds also enable the ADuM3151 to have higher data throughput, providing improved system performance with faster response times.

Analog Devices' ADuM3151 SPIsolator Digital Isolator is rated for up to 125°C, and supports a wide range of high data rate SPI applications, including distributed control systems, programmable logic controllers (PLCs), and sensor isolation monitors used in industrial automation, instrumentation equipment and motor control.
