Description

The SPT7755 is a full parallel (flash) analog-to-digital converter capable of digitizing full scale (0 to 2 V) inputs into
eight-bit digital words at an update rate of 750 MSPS. The ECL-compatible outputs are demultiplexed into two separate output banks, each with differential data ready outputs to ease the task of data capture. The SPT7755's wide input bandwidth and low capacitance eliminate the need for external track-and-hold amplifiers for most applications. A proprietary decoding scheme reduces metastable errors to the 1 LSB level. The SPT7755 operates from a single 5.2 V supply, with a nominal power dissipation of 5.5 W.

The SPT7755 is available in an 80-lead surface-mount MQuad package over the industrial temperature range (25  to +85 ) and in die form.
