Overview
The AD5317ARUZ is a quad 10-bit buffered voltage-output digital-to-analog converter (DAC) produced by Analog Devices Inc. This component is part of the AD5307/AD5317/AD5327 family, which offers high precision and versatility in various applications. The AD5317 operates from a single 2.5 V to 5.5 V supply, consuming 400 µA at 3 V, and is housed in a 16-lead TSSOP package. It features on-chip output amplifiers that allow the outputs to swing rail-to-rail with a slew rate of 0.7 V/µs, making it suitable for a wide range of digital-to-analog conversion needs.
