AD5624BRMZ. (ANALOG DEVICES)

The AD5624BRMZ is a low power quad 12-bit buffered voltage-out Digital-to-analog Converter (DAC) operates from a single 2.7 to 5.5V supply and are guaranteed monotonic by design. The AD5624 requires an external reference voltage to set the output range of the DAC. The part incorporates a power-on reset circuit that ensures the DAC output powers up to 0V and remains there until a valid write takes place. The parts contain a power-down feature that reduces the current consumption of the device to 480nA at 5V and provides software-selectable output loads while in power-down mode. The low power consumption of this part in normal operation makes it ideally suited to portable battery-operated equipment. The AD5624 on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The AD5624 uses a versatile 3-wire serial interface that operates at clock rates up to 50MHz and is compatible with standard SPI®, QSPI™, MICROWIRE™ and DSP interface standards.
