Overview
The AD5339BRMZ-REEL is a 12-bit Digital-to-Analog Converter (DAC) produced by Analog Devices Inc. This component is part of the AD5337/AD5338/AD5339 family, which includes dual 8-, 10-, and 12-bit buffered voltage output DACs, respectively. The AD5339 is housed in an 8-lead MSOP package and operates from a single 2.5 V to 5.5 V supply, consuming 250 μA at 3 V. It features on-chip output amplifiers that allow rail-to-rail output swing and a 2-wire serial interface compatible with SMBus at VDD < 3.6 V, operating at clock rates up to 400 kHz.
