DESCRIPTION The DAC3154/DAC3164 are dual channel 10-/12-BIT, pin-compatible family of 500 MSPS digital-TO-analog CONVERTERS (DAC). The DAC3154/DAC3164 use a 10- /12-BIT wide LVDS digital bus WITH an input FIFO. FIFO input and output pointers can be synchronized across multiple devices for precise signal synchronization. The DAC outputs are current sourcing and terminate TO GND WITH a compliance range of –0.5 TO 1V. DAC3154/ DAC3164 are pin compatible WITH the dual-channel, 14-bit, 500 MSPS digital-TO-analog CONVERTERS DAC3174, and the single channel, 14-/12-10-bit, digital-TO-analog CONVERTERS DAC3171/DAC3161/DAC3151.
