AD5663RBCPZ-3REEL7

AD5663RBCPZ-3REEL7 is a low-power, dual 16bit buffered voltage out digital-to-analogue converter (DAC) that operates from a single 2.7V to 5.5V supply and is guaranteed monotonic by design. It has an on-chip reference. The on-chip reference is off at power-up, allowing the use of an external reference; and this device can be operated from a single 2.7V to 5.5V supply. The internal reference is turned on by writing to the DAC. The parts incorporate a power-on reset circuit that ensures the DAC output powers up to 0V and remains there until a valid write takes place. The part contains a power-down feature that reduces the current consumption of the device to 480nA at 5V and provides software-selectable output loads while in power down mode. Applications include process control, data acquisition systems, portable battery-powered instruments, digital gain and offset adjustment, programmable voltage and current sources, and programmable attenuators.
