Overview
The AD5620ARJZ-2500RL7, produced by Analog Devices Inc., is a member of the nanoDAC™ family of devices. It is a low-power, single, 12-bit, buffered voltage-out digital-to-analog converter (DAC) that is guaranteed monotonic by design. This device features an internal 2.5 V, 5 ppm/°C reference, providing a full-scale output voltage range of 5 V. The AD5620 is available in an 8-lead SOT-23 package and operates over a temperature range of -40°C to +105°C.
