Overview
The AD5338BRMZ-1REEL7, produced by Analog Devices Inc., is a 10-bit digital-to-analog converter (DAC) that features a 2-wire (I2C-compatible) serial interface. This component is part of the AD5337/AD5338/AD5339 family, each offering different resolution levels. The AD5338 is specifically designed for applications requiring a 10-bit resolution. It operates from a single 2.5 V to 5.5 V supply and is housed in an 8-lead MSOP package, making it suitable for space-constrained and low-power designs.
