GENERAL DESCRIPTION

The SPT7863 is a 10-bit monolithic, low-cost, ultralowpower analog-to-digital converter capable of minimum word rates of 40 MSPS. The on-chip track-and-hold function assures very good dynamic performance without the need for external components. The input drive requirements are minimized due to the SPT7863¡¯s low input capacitance of only 5 pF.
