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).
