Overview
The AD5318BRUZ-REEL7, produced by Analog Devices Inc., is a 10-bit octal digital-to-analog converter (DAC) with buffered voltage outputs. This component is part of the AD5308/AD5318/AD5328 family, which includes 8-, 10-, and 12-bit resolutions, respectively. The AD5318 operates from a single supply voltage ranging from 2.5 V to 5.5 V and is housed in a 16-lead TSSOP package. It features a versatile 3-wire serial interface compatible with standard SPI, QSPI, MICROWIRE, and DSP interface standards, allowing for clock rates up to 30 MHz. The device includes on-chip output amplifiers that provide rail-to-rail output swing with a slew rate of 0.7 V/μs, making it suitable for a variety of applications requiring precise analog output control.
