The AD5641BKSZ-500RL7 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. Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. 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. It 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.
