GENERAL DESCRIPTION
The SPT7855 is a 10-bit monolithic, low-cost, ultralow-power analog-to-digital converter capable of minimum word rates of 25 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 SPT7855’s low input capacitance of only 5 pF.
