The AD5641, a member of the nanoDAC family, is a single, 14-bit, buffered, voltage out DAC that operates from a single 2.7 V to5.5 V supply, consuming <100 μA at 5 V. The part comes in a tiny SC70 package. Its on-chip precision output amplifier allowsrail-to-rail output swing to be achieved. The AD5641 utilizes a versatile 3-wire serial interface that operates at clockrates up to 30 MHz and is compatible with SPI®, QSPI™, MICROWIRE™, and DSP interface standards. The reference for AD5641 isderived from the power supply inputs and, therefore, gives the widest dynamic output range. The part incorporates a power-on reset circuit,which ensures that the DAC output powers up to 0 V and remains there until a valid write to the device takes place. The AD5641 contains a power-down feature that reduces current consumption to <100 nA at 3 V, and provides software-selectableoutput loads while in power-down mode. The part is put into power-down mode over the serial interface. The low powerconsumption of the part in normal operation makes it ideally suited to portable battery-operated equipment. The combinationof small package and low power makes this nanoDAC device ideal for level-setting requirements such as generating biasor control voltages in space-constrained and power-sensitive applications.The AD5641 is designed with new technology andcomes in a space-saving SC70 package. |
