Overview
The AD5337BRMZ-REEL, produced by Analog Devices Inc., is a dual 8-bit buffered voltage output Digital-to-Analog Converter (DAC). This component is part of the AD5337/AD5338/AD5339 family, each differing in their resolution (8-bit, 10-bit, and 12-bit respectively). The AD5337 operates from a single 2.5 V to 5.5 V supply and is housed in an 8-lead MSOP package. It is designed for low power consumption, making it suitable for portable battery-operated equipment.
