Texas Instruments DAC31x1
500MSPS Digital-to-Analog Converters

Texas Instruments DAC31x1 500MSPS Digital-to-Analog Converters are a family of single channel 500MSPS digital-to-analog converters with resolutions of 10-/12-/14-bits. The family uses a 10-/12-/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 to 1V. DAC3151/DAC3161/DAC3171 is pin compatible with the dual-channel, 10-/12-/14-bit, 500MSPS digital-to-analog converter DAC3154/DAC3164/DAC3174. The device is available in a QFN-64 PowerPAD™ package is specified over the full industrial temperature range (–40°C to 85°C).
