The is a single 14-bit buffered voltage-out Digital-to-analog Converter DAC operates from a single 2.7 to 5.5V supply, typically consuming 75µA at 5V. The AD5641 uses a versatile 3-wire serial interface that operates at clock rates up to 30MHz and is compatible with SPI®, QSPI™, MICROWIRE™ and DSP interface standards. The reference for AD5641 is derived 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 0V and remains there until a valid write to the device takes place. The AD5641 contains a power-down feature that reduces current consumption typically to 0.2µA at 3V and provides software-selectable output loads while in power-down mode. The part is put into power-down mode over the serial interface. The low power consumption of the part in normal operation makes it ideally suited to portable battery-operated equipment.
