SPT SPT7720
The SPT7720 is an 8-bit, high-speed, analog-to-digital converter implemented in a 0.5 µm BiCMOS process. It utilizes a folding and interpolating architecture that provides both high sample rates and low power. The device comes complete with a high bandwidth track-and-hold amplifier and internal voltage reference.| Part No. | SPT7720 |

GENERAL DESCRIPTION
The SPT7720 digital inputs interface directly to TTL, CMOS or positive ECL (PECL) logic. The digital outputs are user selectable in either single-channel or dual-channel modes. It is a pin-compatible, direct replacement for the AD9054. The SPT7720 is available in a 44-lead TQFP surface mount package over the industrial temperature range of –40 to +85 °C.
