Metastable Errors Reduced to 1 LSB
Monolithic for Low Cost
Gray Code Output
GENERAL DESCRIPTION
The SPT7760 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 1 GSPS. 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 SPT7760's wide input
bandwidth and low capacitance eliminate the need for exter-
nal track-and-hold amplifiers for most applications. A propri-
CLK CLK
etary decoding scheme reduces metastable errors to the
1 LSB level. The SPT7760 operates from a single -5.2 V
supply, with a nominal power dissipation of 5.5 W.
The SPT7760 is available in an 80L surface-mount MQUAD
package over the industrial temperature range. Contact the
factory for availability of die and /883 versions.
