Overview
The AD5339ARMZ, produced by Analog Devices Inc., is a dual 12-bit buffered voltage output Digital-to-Analog Converter (DAC) housed in an 8-lead MSOP package. This component operates from a single 2.5 V to 5.5 V supply, consuming 250 μA at 3 V, making it suitable for low-power applications. The AD5339 features on-chip output amplifiers that allow rail-to-rail output swing with a slew rate of 0.7 V/μs. It is controlled via a 2-wire serial interface compatible with SMBus at VDD < 3.6 V, allowing multiple devices to be placed on the same bus.
