GENERAL DESCRIPTION
The AD9070 is a monolithic sampling analog-to-digital
converter with an on-chip track-and-hold circuit and ECL
digital interfaces. The product operates at a 100 MSPS
conversion rate with outstanding dynamic performance over
its full operating range.
The ADC requires only a single –5 V supply and an encode
clock for full performance operation. The digital outputs are
ECL compatible, while a differential clock input accommodates
a wide range of logic levels. The AD9070 may be operated in a
Positive ECL (PECL) environment with a single +5 V supply.
An Out-of-Range output (OR) is available in the DIP version to
indicate that a conversion result is outside the operating range.
In both package styles, the output data are held at saturation
levels during an out-of-range condition.
The input amplifier supports single-ended interfaces. An
internal –2.5 V reference is included in the SOIC packaged
device (an external voltage reference is required for the
DIP version).
Fabricated on an advanced bipolar process, the AD9070
is available in a plastic SOIC package specified over the
industrial temperature range (–40°C to +85°C), and a full
MIL-PRF-38534 QML version (–55°C to +125°C) in a
ceramic Dual-in-Line Package (DIP).
