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 to indicate that a conversion result is outside the operating range. The output data is held at saturation levels during an out-of-range condition.

The input amplifier supports single-ended interfaces. An internal -2.5 V reference is also included. 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).
