GENERAL DESCRIPTION

The SPT7861 is a 10-bit monolithic, low-cost, ultralow-power analog-to-digital converter capable of minimum word rates of 40 MSPS. This is a pin-compatible improved version of the SPT7860. The on-chip track-and-hold function assures excellent dynamic performance without the need for external components. The input drive requirements are minimized due to the SPT7861¡¯s low input capacitance of only 5 pF.
