Overview
The AD5686RARUZ-RL7, produced by Analog Devices Inc., is a member of the nanoDAC+® family. This quad digital-to-analog converter (DAC) is known for its high relative accuracy, low drift, and compact design. The device features a 16-bit resolution and is available in a tiny 3 mm x 3 mm LFCSP package, as well as a 16-lead TSSOP package. It operates from a single supply voltage of 2.7 V to 5.5 V and includes a 2.5 V internal reference with a drift of 2 ppm/°C. The AD5686RARUZ-RL7 is designed for applications requiring high precision and reliability in a small form factor.
