DESCRIPTION
The LTC®1655/LTC1655L are rail-to-rail voltage output, 16-bit digital-to-analog converters in an SO-8 package. They include an output buffer and a reference. The 3-wire serial interface is compatible with SPI/QSPI and MICROWIRETM protocols. The CLK input has a Schmitt trigger that allows direct optocoupler interface.
