The AD9433 is a 12-bit, 105 MSPS/125 MSPS IF sampling ADC with features such as high SNR, low distortion, and wide application range.
The AD9433 is a 12‑bit pipeline analog‑to‑digital converter designed for IF sampling applications up to 125 MSPS. It features an on‑chip track‑and‑hold circuit, internal reference, and selectable output formats (twos‑complement or offset binary). The device operates from a 5 V analog supply and supports differential encode clocks for optimal performance.
Typical applications include cellular infrastructure, wideband carrier systems, point‑to‑point radios, and radar or satellite ground equipment. The ADC is supplied in a 52‑lead thin quad flat package and is pin‑compatible with the AD9432.
