GENERAL DESCRIPTION

The AD9446 is a 16-bit, monolithic, sampling analog-to-digital converter (ADC) with an on-chip track-and-hold circuit. It is optimized for performance, small size, and ease of use. The product operates up to a 100 MSPS, providing superior SNR for instrumentation, medical imaging, and radar receivers employing baseband (
