Linear Technology LTM2895
The LTM2895 works with DACs and general purpose devices that have a mode (0, 0) SPI interface. The interface enables fast data throughput, which makes the LTM2895 ideally suited for a wide variety of applications. The high speed SPI-compatible serial port supports 1.71V to 5.5V logic supplies.FEATURES

The LTM®2895 is a high speed isolated µModule® (micromodule) SPI interface with DAC control signals designed to isolate LTC’s family of general purpose DACs and to isolate general purpose SPI interfaces. The LTM2895 is targeted at generic SPI and digital-to-analog converter applications. The isolation barrier tolerates large voltage ground variations between the logic interface and the isolated side of the LTM2895.
