GENERAL DESCRIPTION
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.
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.
PRODUCT HIGHLIGHTS
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.
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.
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).
