Overview
The AD5310BRTZ-500RL7, produced by Analog Devices Inc., is a single, 10-bit, buffered voltage output 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 suitable for portable, battery-operated equipment. The device features a versatile 3-wire serial interface compatible with standard SPI™, QSPI™, MICROWIRE®, and DSP interface standards, operating at clock rates up to 30 MHz. The on-chip precision output amplifier allows for rail-to-rail output swing, and the device includes a power-on reset circuit and multiple power-down modes to minimize power consumption.
