GENERAL DESCRIPTION

The AD9229 is a quad, 12-bit, 65 MSPS analog-to-digital converter (ADC) with an on-chip sample-and-hold circuit that is designed for low cost, low power, small size, and ease of use. The product operates at up to a 65 MSPS conversion rate and is optimized for outstanding dynamic performance in applications where a small package size is critical.
