Overview
The AD5328BRUZ-REEL is a 12-bit octal digital-to-analog converter (DAC) produced by Analog Devices Inc. This device is part of the AD5308/AD5318/AD5328 family, which offers resolutions of 8, 10, and 12 bits, respectively. The AD5328 is designed for applications requiring multiple analog outputs with high precision and low power consumption.
It operates from a single supply voltage ranging from 2.5 V to 5.5 V and features on-chip rail-to-rail output buffer amplifiers, ensuring a wide output voltage range. The device is packaged in a 16-lead Thin Shrink Small Outline Package (TSSOP), making it suitable for space-constrained designs.
