The AD9445 is a high-performance 14-Bit, 105/125 MSPS, IF Sampling ADC that features 14-bit resolution, 125 MSPS sample rate and low power consumption. It uses the advanced AD9445BSV-125 chip and has excellent linearity and low noise. This device is suitable for applications such as multicarrier, multimode cellular networks.
The AD9445 is a 14‑bit, monolithic sampling analog‑to‑digital converter (ADC) optimized for high performance, small size, and ease of use. It operates up to 125 MSPS and is intended for multicarrier, multimode cellular receivers, radar, broadband wireless, and medical imaging applications. The device requires 3.3 V and 5.0 V supplies and offers both LVDS and CMOS output options.
The datasheet provides full electrical specifications, timing diagrams, absolute maximum ratings, and thermal resistance data. Optional features allow selectable input ranges, data formats, and output modes, while the RF‑ENABLE pin lets users optimize SFDR for higher sampling frequencies.
