SPT7760
8-BIT, 1 GSPS FLASH A/D CONVERTER
APPLICATIONS
• • • • Digital Oscilloscopes Transient Capture Radar, EW, ECM Direct RF Down-Conversion
FEATURES
• • • • • • 1:2 Demuxed ECL Compatible Outputs Wide Input Bandwidth - 900 MHz Low Input Capacitance - 15 pF (MQUAD) 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 converter capable of digitizing full scale (0 to -2 V) inputs into eight-bit digital words at an update rate of 1 GSPS. The ECLcompatible outputs are demultiplexed into two separate output banks, each with differential data ready outputs to ease the task of data capture.
