AD5668BRUZ-2

The AD5668BRUZ-2 is a low power octal 16-bit buffered voltage-output Digital-to-analog Converter (DAC) operates from a single 2.7 to 5.5V supply. It has a 2.5V, 5ppm/°C reference giving a full-scale output range of 5V. The on-board reference is off at power-up allowing the use of an external reference. The internal reference is enabled via a software write. The part incorporates a power-on reset circuit that ensures that the DAC output powers up to 0V and remains powered up at this level until a valid write takes place. The part contains a power-down feature that reduces the current consumption of the device to 400nA at 5V and provides software- selectable output loads while in power-down mode for any DAC channels. The outputs of DAC can be updated simultaneously using the LDAC function with the added functionality of user-selectable DAC channels to simultaneously update. There is also an asynchronous CLR that updates DAC to user-programmable code-zero scale, midscale or full scale.
