Overview
The AD5317BRU, produced by Analog Devices Inc., is a quad 10-bit buffered voltage-output Digital-to-Analog Converter (DAC) packaged in a 16-lead TSSOP. This device operates from a single 2.5 V to 5.5 V supply, consuming 400 μA 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 AD5317BRU is designed for low power operation and is compatible with standard SPI, QSPI, MICROWIRE, and DSP interface standards, making it versatile for various applications.
