DAC5675A 说明
The DAC5675A is a 14-bit resolution high-speed digital-to-analog converter. The DAC5675A 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 has excellent spurious-free dynamic range (SFDR) at high intermediate frequencies, which makes the DAC5675A well-suited for multicarrier transmission in TDMA- and CDMA-based cellular base transceiver stations (BTSs).
The DAC5675A operates from a single-supply voltage of 3.3V. Power dissipation is 660mW at fCLK = 400MSPS, fOUT = 70MHz. The DAC5675A provides a nominal full-scale differential current output of 20mA, supporting both single-ended and differential applications.
