GENERAL DESCRIPTION
The SPT7755 is a full parallel (flash) analog-to-digital con-
verter 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 sepa-
rate output banks, each with differential data ready out-
puts 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 °C to +85 °C) and in die form.
