DAC3171 (ACTIVE)

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

 

Description

The DAC31x1 is a family of single-channel, 500-MSPS digital-to-analog converters. The family uses a 10-, 12-, and 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. DAC31x1 is pin compatible with the dual-channel, 10-, 12-, and 14-bit, 500-MSPS digital-to-analog converter DAC31x4.

The device is available in a VQFN-64 package which is specified over the full industrial temperature range (–40°C to 85°C).
