Overview
The AD5693RARMZ-RL7, produced by Analog Devices Inc., is a member of the nanoDAC+ family. It is a low-power, single-channel, 16-bit buffered voltage output digital-to-analog converter (DAC). This device is designed for high precision and reliability, making it suitable for a variety of applications requiring accurate voltage output.
The AD5693RARMZ-RL7 operates from a single 2.7 V to 5.5 V supply and features an internal power-on reset circuit that ensures the DAC register is set to zero scale at power-up. The device also includes a power-down mode that reduces current consumption to 2 µA (maximum) at 5 V, enhancing its energy efficiency.
