The AD9239 is a Quad, 12-Bit, 170 MSPS/210 MSPS/250 MSPS Serial Output 1.8V ADC. It features 4 ADC channels, coded serial digital outputs with ECC per channel, an on-chip temperature sensor, -95 dB channel-to-channel crosstalk, 65 dBFS SNR, and 77 dBc SFDR. It offers excellent linearity and a 780 MHz full power analog bandwidth. It is suitable for communication receivers, cable head end equipment/M-CMTS, broadband radios, wireless infrastructure transceivers, and radar/military applications.
The AD9239 is a quad, 12‑bit analog‑to‑digital converter that operates from a single 1.8 V supply and supports sample rates up to 250 MSPS. It offers a full‑power analog bandwidth of 780 MHz, on‑chip temperature sensing, and a high‑speed serial output with error‑correction coding.
The document includes functional block diagrams, timing diagrams, absolute maximum ratings, thermal resistance data, and detailed electrical specifications for the AD9239 family (BCPZ‑170/210/250). It is intended for designers of communication receivers, radar, test equipment, and other high‑frequency applications.
