to isolate LTC’s family of general purpose DACs and to
isolate general purpose SPI interfaces. The LTM2895
works with DACs and general purpose devices that have
a mode (0, 0) SPI interface. nn 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. 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. Uninterrupted communication is maintained …
