GENERAL DESCRIPTION

The SPT7921 A/D converter is the industrys first 12-bit monolithic analog-to-digital converter capable of sample rates greater than 20 MSPS. On board input buffer and track/hold function assures excellent dynamic performance without the need for external components. Drive requirement problems are minimized with an input capacitance of only 5 pF.
