Dual/Quad Converters

Mon, 06/05/2006 - 11:44am

Analog Devices introduces a 16-bit quad D/A converter in a 3 × 3 mm, 10-lead LFCSP. The product is one of eight new dual and quad devices that extend ADI's line of nanoDAC® converters in small packages. The AD5664R offers low power consumption (5 mW at 5 V including reference), making it an suitable 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 ° C reference. In addition to the AD5664R, Analog Devices is introducing seven nanoDAC converters that offer pin-compatible 12 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.
