... The LTC1452 is a multiplying DAC with a full-scale output of twice the reference input voltage. It operates from a single supply of 2.7V to 5.5V. The LTC1453 has an onboard 1.22V reference and a full- scale output of 2.5V. It operates from a single supply of 2.7V to 5.5V. The low power supply current makes the LTC1451 family ideal for battery-powered applications ...

... Reference The LTC1451 includes an internal 2.048V reference, mak- ing 1LSB equal to 1mV (gain of 2). The LTC1453 has an internal reference of 1.22V with a full scale of 2.5V (gain of 2.05). The internal reference output is turned off when the pin is forced above the reference voltage, allowing an external reference to be connected to the reference pin ...

... D IN CS/LD This circuit shows how to use an LTC1453 to make an opto-isolated digitally controlled 4mA to 20mA process controller. The controller circuitry, including the opto- isolation, is powered by the loop voltage that can have a wide range of 3.3V to 30V. The 1.22V reference output of the LTC1453 is used for the 4mA offset current and V is used for the digitally controlled 0mA to 16mA current ...
