The SPT7920 A/D converter is the industry's first 12-bit monolithic analog-to-digital converter capable of sample rates greater than 10 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. Logic inputs and outputs are TTL. An overrange output signal is provided to indicate overflow conditions. Output
