AD9081BBPZ-4D4AC

AD9081BBPZ-4D4AC is Analog Devices’ four-channel, high-speed RF ADC module. It digitizes four independent RF/IF channels simultaneously and outputs data to a host processor or FPGA via a JESD204B-compatible serial interface. The device is aimed at software-defined radio, radar, EW, and other high-bandwidth front-ends needing multi-channel digitization with tight channel alignment.
Key features (high level):
- Four synchronized ADC cores with wide instantaneous bandwidth for RF/IF signals.
- Flexible multi-channel data interface (JESD204B) and clocking for accurate timing alignment.
- Programmable per-channel gain and calibration for high dynamic range and linearity.
- Robust packaging (BBPZ) suitable for compact, multi-board systems.
Applications: telecom infrastructure, SDR receivers, radar/ELINT, and test equipment.
For exact specs, operating conditions, and evaluation boards, check the Analog Devices product page and the AD9081 datasheet. If you want, I can summarize the datasheet’s key numbers.
