Overview
The AD9446BSVZ-80 is a high-performance, 16-bit, monolithic analog-to-digital converter (ADC) produced by Analog Devices Inc. This ADC is optimized for superior performance, small size, and ease of use. It operates at sampling rates up to 80 MSPS and is particularly suited for applications requiring high signal-to-noise ratio (SNR) and spurious-free dynamic range (SFDR), such as instrumentation, medical imaging, and radar receivers employing baseband IF frequencies.
The device features an on-chip track-and-hold circuit and requires 3.3 V and 5.0 V power supplies along with a low voltage differential input clock for full performance operation. It does not require external reference or driver components for many applications, making it a convenient choice for various designs.
