12位170/210/250MSPS的1.8V模數(shù)轉(zhuǎn)換器ad9634數(shù)據(jù)表

　　The AD9634 is a 12-bit， analog-to-digital converter （ADC） with sampling speeds of up to 250 MSPS. The AD9634 is designed to support communications applications where low cost， small size， wide bandwidth， and versatility are desired. The ADC core features a multistage， differential pipelined architecture with integrated output error correction logic. The ADC features wide bandwidth inputs that can support a variety of user-selectable input ranges. An integrated voltage reference eases design considerations. A duty cycle stabilizer （DCS） is provided to compensate for variations in the ADC clock duty cycle， allowing the converter to maintain excellent performance. The ADC output data are routed directly to the external 12-bit LVDS output port. Flexible power-down options allow significant power savings， when desired.Programming for setup and control is accomplished using a 3-wire， SPI-compatible serial interface. The AD9634 is available in a 32-lead LFCSP and is specified over the industrial temperature range of ?40°C to +85°C. This product is protected by a U.S. patent.
