Overview
The AD5339BRMZ-REEL7, manufactured by Analog Devices Inc., is a dual 12-bit buffered voltage output Digital-to-Analog Converter (DAC). This device is part of the AD5337/AD5338/AD5339 family, each offering different bit resolutions. The AD5339BRMZ-REEL7 is housed in an 8-lead MSOP package and operates from a single 2.5 V to 5.5 V supply, making it versatile for various applications.
It features a low power consumption of 250 μA at 3 V and 300 μA at 5 V, and it includes a 2-wire (I2C-compatible) serial interface. The device is designed for high accuracy and reliability, with guaranteed monotonic behavior over all codes and a power-on reset to 0 V.
