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 applica-

tions. 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 combi-

nation 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).

PRODUCT HIGHLIGHTS

Low Power—Just 275 mW power dissipation per channel at

105 MSPS. Other speed grade proportionally scaled down while

maintaining high ac performance.

Pin Compatibility Upgrade—Allows easy migration from 8-bit

to 10-bit. Pin-compatible with the 8-bit AD9288 dual ADC.

Ease of Use—On-chip reference and user controls provide flex-

ibility in system design.

High Performance—Maintain 54 dB SNR at 105 MSPS with a

Nyquist input.

Channel Crosstalk—Very low at –75 dBc.
