Teledyne SP Devices has announced its 12-bit ADQ35 digitizer, designed to offer a combination of speed, resolution and flexibility for demanding scientific, industrial and OEM applications.
Applications and market demand
The ADQ35 is designed for use in applications such as swept source optical coherence tomography (SS-OCT), time-of-flight mass spectrometry, distributed fiber-optic sensing, lidar, scientific instrumentation and automated test equipment. These systems require digitizers that can capture and process large volumes of data with high accuracy and low latency.
To meet these requirements, the ADQ35 provides multi-GSPS performance, efficient real-time processing and high-speed data transfer. It can be positioned close to the detector to help maintain signal integrity, particularly in compact or noise-sensitive environments.
Performance and technical highlights
The ADQ35 offers dual-channel sampling at 5GSPS or single-channel operation at 10GSPS, with 12bit vertical resolution. Its DC-coupled analog front end provides up to 2.5GHz input bandwidth and a 0.5Vpp input range. An onboard 8GB memory supports extended data capture.
For high-throughput applications, the device supports peer-to-peer GPU streaming at rates up to 14GB/s, enabling real-time data transfer. Additional features include programmable DC offset and availability in both PCIe and USB 3.2 form factors to support flexible system integration.
Firmware and FPGA options
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 digitizer.
