GENERAL DESCRIPTION
The SPT7938 is a 12-bit monolithic, low-cost, low-power 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 SPT7938’s low input capacitance of only 20 pF.
