LTC1655 16-Bit Rail-to-Rail Micropower DAC in SO-8 Package Features s s s s s s s s s s DESCRIPTIO 16-Bit Monotonicity Over Temperature Deglitched Rail-to-Rail Voltage Output SO-8 Package 5V Single Supply Operation ICC(TYP): 600µA Internal Reference Maximum DNL Error: 1LSB Power-On Reset 3-Wire Cascadable Serial Interface Low Cost The LTC®1655 is a rail-to-rail voltage output, 16-bit digital-to-analog converter (DAC) in an SO-8 package. It includes an output buffer and a reference. The 3-wire serial interface is patible with SPI/QSPI and MICROWIRETM 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 3.0m W on a single 5V supply. The LTC1655 is pin patible with Linear Technology’s 12-bit VOUT DAC family, allowing an easy upgrade path. It is the only buffered 16-bit DAC in an SO-8 package and it includes an onboard reference for stand alone performance. , LTC and LT are registered trademarks of Linear Technology Corporation.
