Overview
The AD9446BSVZ-100 is a high-performance, 16-bit, monolithic analog-to-digital converter (ADC) designed by Analog Devices Inc. This ADC is optimized for superior performance, compact size, and ease of use. It operates at sampling rates up to 100 MSPS, making it suitable for various high-speed applications such as instrumentation, medical imaging, and radar receivers. The device features an on-chip track-and-hold circuit and requires 3.3 V and 5.0 V power supplies for full performance operation. It does not require external reference or driver components for many applications, and its data outputs are compatible with both CMOS and LVDS (ANSI-644) standards.
