Working Principles

The LTC2645IMS-L12#TRPBF is a digital-to-analog converter that converts digital input data into an accurate analog voltage output. It utilizes a 12-bit resolution to provide precise control over the output voltage. The device communicates with a microcontroller or other digital devices through a serial interface (SDA, SCL). The reference voltage (REF) determines the maximum output voltage, which can be set within the supply voltage range. The chip select (CS) and load DAC (LDAC) pins control the conversion and update of the analog output.
