GENERAL DESCRIPTION
The AD9633 is a quad, 12-bit, 80 MSPS/105 MSPS/125 MSPS analog-to-digital converter (ADC) with an on-chip sample-andhold circuit designed for low cost, low power, small size, and ease of use. The product operates at a conversion rate of up to 125 MSPS and is optimized for outstanding dynamic performance and low power in applications where a small package size is critical.
