Quad, 16 Bit D/A Converter With 10ppm/°C Max On-Chip Reference In 14-Lead TSSOP

The AD5666 DAC is a low power, quad, 16-bit buffered voltage-out DAC The part operates from a single +2.7 V to +5.5 V, and is guaranteed monotonic by design.
The AD5666 has an on-chip reference with an internal gain of two. The AD5666-1 has a 1.25 V 10 ppm/C max reference and the AD5666-2 has a 2.5 V 10ppm/C max reference. The onboard reference is off at power-up allowing the use of an external reference. The internal reference is turned on by writing to the DAC The part incorporates a power-on-reset circuit that ensures that the DAC output powers up to zero volts (POR pin low) or midscale (POR pin high) 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 200 nA at 5 V and provides software selectable output loads while in power-down mode for any or all DACs channels.
The outputs of all DACs may be updated simultaneously using the /LDAC function, with the added functionality of selecting through software any number of DAC channels to synchronize. There is also an asynchronous active low /CLR that clears all DACs to a software selectable code - 0 V, midscale or fullscale .
The AD5666 utilizes a versatile three-wire serial Interface that operates at Clock rates up to 50 MHz and is compatible with standard SPI, QSPI, MICROWIRE and DSP Interface standards. Its on-chip precision output Amplifier allows rail-torail output swing to be achieved.
Product Highlights 1. Quad 16-Bit DAC; 12-Bit Accuracy Guaranteed. 2. On-chip 1.25/2.5V, 10ppm/C max Reference. 3. Available in 14-lead TSSOP package. 4. Selectable Power-On-Reset to Zero volts or Midscale. 5. Power-down capability. When powered down, the DAC typically consumes 50 nA at 3 V and 200 nA at 5 V.
