The LTC1655LIS8#TRPBF is a part of low-power high-precision 12-bit digital-to-analog converters (DACs) that belong to the family of Data Acquisition components. This particular device is the simplest of its type, allowing the user to easily control its operation via a single input port of 8-bit data resolution. The key features of this device are its wide range of output voltage (41.47V) and full-scale accuracy (down to ±1/32 LSB or 0.0035%). This makes the LTC1655LIS8#TRPBF ideal for both low- and high-resolution digital-to-analog conversion applications.The primary application field of the LTC1655LIS8#TRPBF is in digital test equipment, communication systems, audio systems, and other applications where precise analog control and precision voltage outputs are needed. The main advantage over other family products is the low power consumption (just 15 mW in normal mode).The Working Principle of the LTC1655LIS8#TRPBF DAC is based on the digital/analog conversion process. This device receives digital information from the microcontroller, which is then converted into an analog voltage level by the DAC\'s internal circuit. The output of the DAC is proportional to the input digital code, so the voltage range of the analog output can be adjusted accordingly.The LTC1655LIS8#TRPBF DAC has an onboard 2to1 multiplexer, allowing heavier loads to be driven without compromising the accuracy of the analog voltage output. This also increases the total current capability of the device to 15 mA (when powered with a 5V supply) which is ideal for powering multiple loads. Furthermore, the LTC1655LIS8#TRPBF DAC also features an onboard programmable gain amplifier (PGA), allowing the user to adjust the gain of the device to suit their application.To summarise, the LTC1655LIS8#TRPBF is a low-power 12-bit digital-to-analog converter that is ideal for applications requiring precise analog control and precision voltage outputs. It has a wide range of output voltage and full-scale accuracy down to 0.0035%. The onboard programmable gain amplifier and 2to1 multiplexer make it suitable for powering multiple loads, while the low power consumption ensures reliable performance.
