Overview
The AD5300BRTZ-500RL7 is a single, 8-bit buffered voltage output Digital-to-Analog Converter (DAC) manufactured by Analog Devices Inc. This device operates from a single supply voltage ranging from 2.7 V to 5.5 V and consumes 115 μA at 3 V, making it suitable for low-power applications. The AD5300 features an on-chip precision output amplifier that allows for rail-to-rail output swing, ensuring a wide dynamic output range. It also includes a power-on-reset circuit that sets the DAC output to zero volts until a valid write operation is performed, and a power-down feature that reduces current consumption to 200 nA at 5 V.
