General Description
AD9218 General Description
The AD9218 is a dual 10-bit monolithic sampling analog-to-digital converter with on-chip track-and-hold circuits and is optimized for low cost, low power, small size and ease of use. The product 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 an encode 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 are available to 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. Fabricated on an advanced CMOS process, the AD9218 is available in a 48-lead surface-mount plastic package (7 * 7 mm
LQFP) specified over the industrial temperature range (40°C to +85°C).
