14位80/105/125/150MSPS的1.8V双模数转换器AD9640数据表

　　Integrated dual 14-bit， 80/105/125/150 MSPS ADC. 2. Fast overrange detect and signal monitor with serial output. 3. Signal monitor block with dedicated serial output mode. 4. Proprietary differential input that maintains excellent SNR performance for input frequencies up to 450 MHz. 5. Operation from a single 1.8 V supply and a separate digital output driver supply to accommodate 1.8 V to 3.3 V logic families. 6. A standard serial port interface that supports various product features and functions， such as data formatting （offset binary， twos complement， or gray coding）， enabling the clock DCS， power-down， and voltage reference mode. 7. Pin compatibility with the AD9627， AD9627-11， and the AD9600 for a simple migration from 14 bits to 12 bits， 11 bits， or 10 bits.
