10位40/65/80/105MSPS 3伏的無源定位雙模擬數(shù)字轉(zhuǎn)換器AD9218數(shù)據(jù)表

　　The AD9218 is a dual 10-bit monolithic sampling analog-todigital converter with on-chip track-and-hold circuits. The product is low cost， low power， and is small and easy to use. The AD9218 operates at a 105 MSPS conversion rate with outstanding dynamic performance over its full operating range. Each channel can be operated independently. The ADC requires only a single 3.0 V （2.7 V to 3.6 V） power supply and a clock for full operation. No external reference or driver components are required for many applications. The digital outputs are TTL/CMOS compatible and a separate output power supply pin supports interfacing with 3.3 V or 2.5 V logic. The clock input is TTL/CMOS compatible and the 10-bit digital outputs can be operated from 3.0 V （2.5 V to 3.6 V） supplies. User-selectable options offer a combination of power-down modes， digital data formats， and digital data timing schemes. In power-down mode， the digital outputs are driven to a high impedance state.
