SnipCard DAC 16 bit – 2 channels 0-10V unbuffered

DAC 16 bit dual channel SnipCard for Archiduino System (or Arduino, if used as breakout board).

This SnipCard gives Archiduino two accurate 16 bit DAC outputs thanks to the AD5663 made by Analog Devices. With breadbording cables you can easily adapt it to work with every Arduino board model. The outputs are buffered through the reliable LM7322 op-amp.

Techical specifications:

The AD5663, a member of the nanoDAC® family, is a low power, dual, 16-bit buffered voltage-out DAC that operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design.
The AD5663 requires an external reference voltage to set the output range of the DAC. The part incorporates a power-on reset circuit that ensures the DAC output powers up to 0 V or midscale (AD5663BRMZ-1) 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 480 nA at 5 V and provides software-selectable output loads while in powerdown mode.   (from AD5662 datasheet).

The output channel are secured by a dual-line ESD-protection diode (according to IEC 61000-4-2: ± 30 kV contact discharge, ± 30 kV air discharge)

The 16 bit DAC SnipCard voltage reference is provided by a LT1236 made by Linear Technology.

The LT® 1236 is a precision reference that combines ultralow drift and noise with excellent long-term stability and high output accuracy. The reference output will both source and sink up to 10mA and is almost totally immune to input voltage variations. The LT1236 combines both superior accuracy and temperature coefficient specifications without the use of high power, on-chip heaters. The LT1236 references are based on a buried zener diode structure which eliminates noise and stability problems with surface breakdown devices. Further, a subsurface zener exhibits better temperature drift and time stability than even the best band-gap references. (from LT1236 datasheet)
