Overview
The AD7303BRZ-REEL, produced by Analog Devices Inc., is a dual 8-bit voltage output digital-to-analog converter (DAC). This component operates from a single supply voltage ranging from +2.7 V to +5.5 V, making it suitable for battery-powered applications. The AD7303 features on-chip precision output buffers that enable rail-to-rail operation, and it includes a versatile 3-wire serial interface compatible with SPI, QSPI, and Microwire standards. This DAC is designed for low power consumption and high-speed serial communication, with a clock rate of up to 30 MHz.
