Описание

The DAC3151, DAC3161, and DAC3171 (DAC31x1) are a family of single-channel, 500-MSPS digital-to-analog converters (DACs). This family uses a 10-, 12-, or 14-bit wide LVDS digital bus with an input FIFO. The 14-bit DAC3171 also supports a DDR 7-bit LVDS interface mode. 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 V to +1 V. The DAC31x1 are pin compatible with the DAC31x4, dual-channel, 10-, 12-, and 14-bit, 500-MSPS digital-to-analog converters.The DAC31x1 are available in a VQFN-64 package that is specified over the full industrial temperature range (–40°C to +85°C).
