GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

The AD9218 is a dual 10-bit monolithic sampling analog-to-

digital 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.

1. Low Power. Only 275 mW power dissipation per channel

at 105 MSPS. Other speed grades proportionally scaled

down while maintaining high ac performance.

2. Pin Compatibility Upgrade. Allows easy migration from 8-bit

to 10-bit devices. Pin compatible with the 8-bit AD9288

dual ADC.

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.

3. Easy to Use. On-chip reference and user controls provide

flexibility in system design.

4. High Performance. Maintains 54 dB SNR at 105 MSPS

with a Nyquist input.

5. 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 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.

6. Fabricated on an Advanced CMOS Process. Available in a

48-lead low profile quad flat package (7 mm × 7 mm

LQFP) specified over the industrial temperature range

(−40°C to +85°C).
