The ADQ35 digitizer by Teledyne SP Devices is engineered for use in areas like swept source optical coherence tomography (SS OCT), time of flight mass spectrometry, distributed fibre-optic sensing, LiDAR, scientific instrumentation, and automated test equipment. These applications require digitizers capable of capturing and processing large volumes of data with high fidelity and minimal latency. To meet these requirements, the ADQ35 delivers multi GSPS performance, efficient real-time processing, and high-speed data transfer — often positioned close to the detector to maintain signal integrity in compact or noise sensitive environments.
The ADQ35 provides dual‑channel sampling at 5 GSPS or single‑channel operation at 10 GSPS, all with 12‑bit vertical resolution. Its DC‑coupled analog front end supports up to 2.5 GHz of input bandwidth with a 0.5 Vpp input range, and the 8 Gbyte onboard memory enables extended data capture. For high‑throughput applications, peer‑to‑peer streaming to GPUs reaches up to 14 Gbyte/s, supporting real‑time data transfer.
Additional features include programmable DC offset and availability in both PCIe and USB 3.2 form factors for flexible system integration.
The ADQ35 supports a range of application‑specific firmware packages, including standard data acquisition, waveform averaging, pulse detection, and SS‑OCT signal conditioning. For users requiring custom real‑time digital signal processing, the open AMD Kintex Ultrascale KU115 FPGA offers extensive resources for implementing tailored DSP directly on the digitiser. This reduces the need for post‑processing and enables real‑time decision‑making — an advantage for OEMs and researchers developing specialised solutions.
