GENERAL DESCRIPTION
The AD9288 is a dual 8-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 100 MSPS conversion rate with out-
standing 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.
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 are available to offer a combi-
nation 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 avail-
able in a 48-lead surface mount plastic package (7
×
7 mm,
1.4 mm LQFP) specified over the industrial temperature range
(–40
°
C to +85
°
C).
