Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The DAC8501 uses a versatile 3-wire serial interface that operates at clock rates up to 30MHz and is patible with standard SPI™, QSPI™, Microwire™, and Digital Signal Processor (DSP) interfaces. The DAC8501 requires an external reference voltage to set the output range of the DAC. The DAC8501 incorporates a power-on reset circuit that ensures that the DAC output powers up at 0V and remains there until a valid write takes place to the device. The DAC8501 contains a power-down feature , accessed over the serial interface, that reduces the current consumption of the device to 200n A at 5V. The low-power consumption of this part in normal operation makes it ideally suited to portable battery-operated equipment. The power consumption is 1.2m W at 5V reducing to 1µW in power-down mode. The DAC8501 is available in an MSOP-8 package. SPI and QSPI are registered trademarks of Motorola. Microwire is a registered trademark of National Semiconductor.
