Overview
The AD5683BCPZ-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 operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design. The AD5683BCPZ-RL7 includes an internal 2.5 V reference with a 2 ppm/°C drift, which is enabled by default. The output span can be programmed to be 0 V to VREF or 0 V to 2 × VREF. The device features a versatile 3-wire serial interface that operates at clock rates of up to 50 MHz and includes a power-down mode that reduces current consumption to 2 µA (maximum) at 5 V.
