Overview
The AD5307ARUZ from Analog Devices Inc. is a quad 8-bit buffered voltage-output Digital-to-Analog Converter (DAC) housed in a 16-lead TSSOP package. This device operates from a single supply voltage ranging from 2.5 V to 5.5 V and consumes a low current of 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 AD5307ARUZ is designed for versatility, utilizing a 3-wire serial interface compatible with standard SPI, QSPI, MICROWIRE, and DSP interface standards, operating at clock rates up to 30 MHz.
