... V operates from a single 2.7V to 5.5V supply. The typical power supply current is 270 A. The low power supply current makes the LTC1658 ideal for battery-powered applications. The space saving MSOP provides the smallest 14-bit DAC system available. , LTC and LT are registered trademarks of Linear Technology Corporation. ...

... CS/LD signal is pulled high to update all of them simultaneously. Voltage Output The LTC1658 rail-to-rail buffered output can source or sink 5mA over the entire operating temperature range while pulling to within 400mV of the positive supply voltage or ground. The output swings to within a few millivolts of ei- ...

... LTC1658 U U APPLICATIONS INFORMATION Rail-to-Rail Output Considerations In any rail-to-rail DAC, the output swing is limited to voltages within the supply range. If the DAC offset is negative, the output for the lowest codes limits shown in Figure 1b. Similarly, limiting can occur near full scale when the REF pin is tied to V ...

... CLK D IN CS/LD This circuit shows how to use an LTC1658 to make an optoisolated digitally controlled 4mA to 20mA process controller. The controller circuitry, including the optoisolation, is powered by the loop voltage that can have a wide range of 3.8V to 30V. The 3.3V output of the LT1121-3.3 is used for the 4mA offset current and V ...
