Working Principles

The LTC2657BCFE-H16 is a digital-to-analog converter (DAC) that converts digital signals into analog voltages. It utilizes a 16-bit resolution to achieve high precision and accuracy in the conversion process. The DAC accepts digital input data through the SPI interface and generates corresponding analog output voltages.

The reference voltage, provided externally, determines the maximum output voltage range. The DAC's internal circuitry converts the digital input data into an analog voltage proportional to the reference voltage. The output voltage can be adjusted within the specified range by varying the digital input.
