The AD9613 is a dual 12-bit， analog-to-digital converter （ADC） with sampling speeds of up to 250 MSPS. The AD9613 is designed to support communications applications where low cost， small size， wide bandwidth， and versatility are desired. The dual ADC cores feature a multistage， differential pipelined architecture with integrated output error correction logic. Each ADC features wide bandwidth inputs supporting a variety of userselectable 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 converters to maintain excellent performance. The ADC output data is routed directly to the two external 12-bit LVDS output ports and formatted as either interleaved or channel multiplexed. 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 AD9613 is available in a 64-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.
