Overview
The AD5300BRM, produced by Analog Devices Inc., is a single, 8-bit buffered voltage-out Digital-to-Analog Converter (DAC) designed for a wide range of applications. It operates from a single supply voltage of 2.7 V to 5.5 V and consumes a low current of 115 µA at 3 V, making it ideal for portable battery-operated equipment. The device features an on-chip precision output amplifier that allows for rail-to-rail output swing, ensuring a wide dynamic output range. The AD5300BRM is part of a family of pin-compatible DACs, including the 10-bit AD5310 and the 12-bit AD5320.
