Overview
The AD5318BRUZ-REEL, produced by Analog Devices Inc., is a 10-bit octal buffered voltage output Digital-to-Analog Converter (DAC) packaged in a 16-lead TSSOP. This device operates from a single supply voltage ranging from 2.5 V to 5.5 V and consumes a typical current of 0.7 mA at 3 V. It features on-chip output amplifiers that allow the outputs to swing rail-to-rail with a slew rate of 0.7 V/μs. The AD5318 uses a versatile 3-wire serial interface compatible with standard SPI, QSPI, MICROWIRE, and DSP interface standards, operating at clock rates up to 30 MHz.
