LTC1655L 16-Bit Rail-to-Rail Micropower DACs inSO-8 Package

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 MICROWIRE™ protocols. The CLK input has a Schmitt trigger that allows direct optocoupler interface. The LTC1655 has an onboard 2.048V reference that can be overdriven to a higher voltage. The output swings from 0V to 4.096V when using the internal reference. The typical power dissipation is 3.0mW on a single 5V supply. The LTC1655L has an onboard 1.25V reference that can be overdriven to a higher voltage. The output swings from 0V to 2.5V when using the internal reference. The typical power dissipation is 1.8mW on a single 3V supply. The LTC1655/LTC1655L are pin compatible with linear Technology’s 12-bit VOUT DAC family, allowing an easy upgrade path. They are the only buffered 16-bit DACs in an SO-8 package and they include an onboard reference for standalone performance
