Overview
The AD5318ARUZ is a 10-bit octal buffered voltage output Digital-to-Analog Converter (DAC) produced by Analog Devices Inc. This component is part of the AD5308/AD5318/AD5328 family, which includes 8-, 10-, and 12-bit resolutions, respectively. The AD5318ARUZ operates from a single supply voltage ranging from 2.5 V to 5.5 V and is housed in a 16-lead Thin Shrink Small Outline Package (TSSOP). It is designed for low power consumption, typically 0.7 mA at 3 V, and features on-chip output buffer amplifiers that allow rail-to-rail output swing with a slew rate of 0.7 V/μs.
