GENERAL DESCRIPTION
The EB7820/24 evaluation board demonstrates the performance of the SPT7820 and SPT7824, monolithic high speed analog-to-digital converters (ADCs). This document can used as an application note and as supplemental information to the existing data sheets (SPT7820 or SPT7824). Both the SPT7820 and SPT7824 have analog input ranges of ±2 V.
The SPT7820 is capable of digitizing an analog input signal into 10-bit words at a minimum update rate of 20 MSPS, while the SPT7824 is capable of digitizing an analog input signal into 10-bit words at a minimum update rate of 40 MSPS. Both devices are pin-compatible. All input/output logic is TTL compatible.
