The SPT7720 is an 8-bit,high-speed,analog-to-digitalconverter implemented in a 0.5 µm BiCMOS process.It utilizes a folding and interpolating architecture that pro-vides both high sample rates and low power. The devicecomes complete with a high bandwidth track-and-hold amplifier and internal voltage reference.

The SPT7720 digital inputs interface directly to TTL,CMOS or positive ECL (PECL) logic. The digital outputsare user selectable in either single-channel or dual-chan-nel modes. It is a pin-compatible, direct replacement forthe AD9054. The SPT7720 is available in a 44-lead TQFPsurface mountpackage over the industrial temperaturerange of-40 to +85 .
