GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

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.

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.

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.

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

Nyquist input.

Channel Crosstalk—Very low at –75 dBc.

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).
