Overview
The AD5683RARMZ-RL7 is a low-power, single-channel, 16-bit buffered voltage output digital-to-analog converter (DAC) from Analog Devices Inc. It belongs to the nanoDAC+® series and features an internal power-on reset circuit that ensures the DAC register is set to zero scale at power-up. The device includes an internal output buffer configured in normal mode and a power-down mode that reduces current consumption to 2µA (maximum) at 5V. It uses a versatile 3-wire serial interface operating at clock rates up to 50MHz, making it suitable for various applications such as process controls, data acquisition systems, digital gain and offset adjustment, and programmable voltage sources.
