Overview
The AD5324BRM-REEL7, produced by Analog Devices Inc., is a quad 12-bit buffered voltage output digital-to-analog converter (DAC) designed for high precision and low power consumption. This component is housed in a 10-lead Mini Small Outline Package (MSOP) and operates from a single 2.5 V to 5.5 V power supply. It is particularly suited for applications requiring multiple DACs with simultaneous output updates and low power operation, making it ideal for portable battery-powered instruments and industrial process control systems.
