Working Principles

The AD9747BCPZRL is a digital-to-analog converter that converts digital signals into analog voltages. It utilizes a 14-bit resolution to accurately represent the digital input values. The device operates at a high sampling rate of up to 250 MSPS, allowing it to process high-frequency signals effectively.

The DAC communicates with a microcontroller or other digital devices through a serial peripheral interface (SPI). This interface enables easy control and configuration of the DAC's settings. The AD9747BCPZRL also features a power-down mode, which reduces power consumption when the device is not in use.

To ensure proper operation, an external voltage reference (VREF) is required. This reference voltage determines the maximum output voltage range of the DAC. The AD9747BCPZRL is designed to operate within a temperature range of -40°C to +85°C.
