GENERAL DESCRIPTION
The SPT7852 has two 10-Bit CMOS analog-to-digital converters that can sample data at speeds up to 20 MSPS. It has excellent low noise performance with a very low typical power dissipation of only 160 mW—that’s the total power for both converters. The SPT7852 uses a dual configuration of the proprietary circuit design found in our 10-bit CMOS single converter family, to achieve its high performance in a CMOS process.
