DAC3171 - 14-bit, 500-MSPS Digital-to-Analog Converter (DAC)

The DAC3151, DAC3161, and DAC3171 (DAC31x1) are a family of single-channel, 500-MSPSdigital-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 aDDR 7-bit LVDS interface mode. FIFO input and output pointers can be synchronized across multipledevices for precise signal synchronization. The DAC outputs are current sourcing, and terminate toGND 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 industrialtemperature range (–40°C to +85°C).
