GENERAL DESCRIPTION

The AD9288 is a dual 8-bit monolithic sampling analog-to-

digital converter with on-chip track-and-hold circuits. It is

optimized for low cost, low power, small size, and ease of use.

The product operates at a 100 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-performance 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.

Information furnished by Analog Devices is believed to be accurate and reliable.

The Encode input is TTL/CMOS-compatible, and the 8-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 standby

modes, digital data formats, and digital data timing schemes. In

standby mode, the digital outputs are driven to a high

impedance state.

Fabricated on an advanced CMOS process, the AD9288 is

available in a 48-lead surface-mount plastic package (7 mm ×

7 mm, 1.4 mm LQFP) specified over the industrial temperature

range (–40°C to +85°C). The AD9288 is pin-compatible with

the 10-bit AD9218, facilitating future system migrations.
