Overview
The AD5317BRU-REEL is a quad 10-bit buffered voltage-output digital-to-analog converter (DAC) produced by Analog Devices Inc. This device is part of the AD5317 series and is packaged in a 16-lead TSSOP (Thin Shrink Small Outline Package). It operates from a single 2.7 V to 5.5 V supply and is known for its low power consumption and high performance.
The AD5317BRU-REEL features on-chip output amplifiers that allow the outputs to swing rail-to-rail, and it includes a versatile 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards. The device is guaranteed monotonic by design over all codes, ensuring reliable and accurate output.
