NXP high-speed, highperformance dual 14-bit, 125 Msps DAC1401D125 DAC1401D125 Lowest power consumption for your cost-effective I/Q transmit application Operating with high update rates of up to 125 Msps, the DAC1401D125 DAC1401D125 from NXP Semiconductors offers exceptional dynamic performance whilst maintaining low power consumption. Key benefits Optimized for I/Q transmit applications -40 % power consumption versus competitor 1.8V / 3.3V / 5.0V input data path compliance Easy to implement (wide operating window in clock period) Pin-to-pin compatible AD9767 AD9767, DAC2904 DAC2904, DAC5672 DAC5672 Key features 14-bit resolution, up to 125 Msps update rate Dual port or interleaved data Excellent SFDR and IMD: 80 dBc Fully independent gain control Single +3.3V supply operation Power dissipation: < 185 mW @ 3.3 V Power down mode: 16.5 mW @ 3.3v 48 lead LQFP package Key applications Communications (basestation, WLAN, WLL) Quadrature modulator Direct Digital Synthesis (DDS) VDSL / AWG Medical / test instrumentation The DAC1401D125 DAC1401D125 is a high-speed, high-performance dual 14 bit digital-to-analog data converter designed for I/Q transmit applications and for applications where board space and power consumption are at a premium. The DAC1401D125 DAC1401D125 can operate with its own individual digital inputs, as well as interleaved DACs where data is alternately written from a single digital input path to either of the two DACs. The DAC full-scale current can be reduced for lower power operation, and a sleep mode is provided for low power idle periods. The DAC1401D125 DAC1401D125 is available in a LQFP48 LQFP48 package, and is specified over the extended industrial temperature range of -40 deg C to +85 deg C. Pin-to-pin compatible with family members DAC1201D125 DAC1201D125 (12 bit) and DAC1001D125 DAC1001D125 (10 bit).
