Analog Devices introduces an 16-bit quad DAC (digital-to-analog converter) in a 3mm x 3mm, 10-lead LFCSP (lead frame chip scale package) – a development that will free up to 70% more board space. The DAC is one of eight dual and quad devices announced today that extend ADI’s line of nanoDAC converters in small packages. The AD5664R offers power consumption of 5 mW at 5 V including reference, making it an choice for designers of industrial and communications products such as PLC cards, analog I/O boards and base stations which require high resolution in the minimum board space. It integrates four buffered 16-bit D/A converters in addition to an on-chip 1.25-V, 5-ppm per degree C reference.
Expanding the nanoDAC family
In addition to the AD5664R, Analog Devices today is introducing seven nanoDAC converters that offer pin compatible 12-bit to 16-bit resolution in dual and quad configurations with and without on-chip references: the quad AD5624, AD5624R, AD5644R and AD5664, and the dual AD5643R, AD5663 and AD5663R. All devices incorporate a power-on reset and a per-channel power-down mode that, in the quad-channel devices, reduces the current consumption of the device to 480 nA at 5 V. In addition, the dual channel devices offer hardware LDAC and CLR functionality and the on-chip precision output amplifier allows rail-to-rail output swing to be achieved, maximising dynamic range and enabling the device to deliver the performance needed in control and level-setting applications.
Pricing and Availability
The AD5664R, along with the other quad and dual nanoDAC devices announced today, are currently sampling and will be available in full production volumes in April 2006. In addition to the 10-lead LFCSP, all devices are available in 10-lead MSOP (mini-small-outline package). Per-unit pricing ranges from $5.49 to $11.40 for the quad devices and from $5.05 to $6.90 for the dual devices—based on resolution and the inclusion of the on-chip reference—in 1,000-piece quantities.
