GENERAL DESCRIPTION
The AD9071 is a monolithic sampling analog-to-digital con-
verter with an on-chip track-and-hold circuit and TTL/CMOS
digital interfaces. The product operates at a 100 MSPS conver-
sion 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 TTL
compatible. Separate output power supply pins support
interfacing with 3.3 V or 5 V logic. An out-of-range output
(OR) is available that indicates a conversion result is outside the
operating range. The output data are held at saturation levels
during an out-of-range condition.
The input amplifier supports differential or single-ended inter-
faces. An internal reference is included.
Fabricated on an advanced BiCMOS process, the AD9071 is
available in a plastic SOIC package specified over the industrial
temperature range (–40 C to +85 C).
