Working Principle

The working principle of the LTC2635CUD-LZ8#TRPBF is based on the conversion of digital signals into an analog signal. The device connects to an external source that supplies digital data to the device, which is then converted into an analog output voltage. The digital-to-analog conversion is accomplished by a low-noise digital to analog converter. The device features an 8-bit resolution, meaning that a total of 256 values can be represented.

The device features an inverse logic select input, which allows the user to specify the polarity of the digital-to-analog conversion. When the inverse logic select input is low, the device interprets the digital input as a binary number. When the inverse logic select input is high, the device interprets the digital input as an offset binary number. This feature allows the device to accurately convert digital signals into precisely measured analog signals.
