Parts are not warranted for performance on full MIL specified temperature range of –55°C to 125°C or operating life.
产品说明

The DAC5675A-SP is a radiation-tolerant, 14-bit resolution high-speed digital-to-analog converter (DAC) primarily suited for space satellite applications. The DAC5675A-SP is designed for high-speed digital data transmission in wired and wireless communication systems, high-frequency direct digital synthesis (DDS), and waveform reconstruction in test and measurement applications. The DAC5675A-SP has excellent SFDR at high intermediate frequencies, which makes it well suited for multicarrier transmission in TDMA and CDMA based cellular base transceiver stations (BTSs).

The DAC5675A-SP operates from a single supply voltage of 3.3 V. Power dissipation is 660 mW at ƒCLK=400 MSPS, ƒOUT = 70 MHz. The DAC5675A-SP provides a nominal full-scale differential current output of 20 mA, supporting both single-ended and differential applications. The output current can be directly fed to the load with no additional external output buffer required. The output is referred to the analog supply voltage AVDD.

The DAC5675A-SP includes a low-voltage differential signaling (LVDS) interface for high-speed digital data input. LVDS features a low differential voltage swing with a low constant power consumption across frequency, allowing for high-speed data transmission with low noise levels (low electromagnetic interference (EMI)).
