精密宽带宽解决方案
精密宽带宽信号链带来了优化测量和驱动解决方案的特定应用参数所需的洞察和灵活性。凭借快速采样速率，该信号链在确保精度的同时，还可充分考虑AC和DC精度之间的权衡，并具备覆盖DC至1 MHz的带宽，满足测量或信号生成需求。利用ADI公司的产品，无论是测量噪声(SNR)、DC线性度、稳定时间性能、闭环或测量延迟，还是总谐波失真(THD)，都能轻松构建满足核心需求的多样化解决方案。
Values and Benefits
Fast precision signal chains offer curated solutions that combine precision amplifiers, analog-to-digital converters (ADCs), digital-to-analog converters (DACs), circuit protection, voltage references, and isolation components, allowing system designers to explore solutions that can be optimized for both precision and speed.
These solutions offer the flexibility to modify parameters such as resolution, gain, and bandwidth to meet system requirements. They cover applications such as hardware-in-the-loop (HIL), nondestructive test, scanning electron microscopes (SEM), and flow cytometry, where speeds above 100 kHz and SNR >85 dB are required.
Optimized latency and feedback
Sampling rates up to 40 MSPS
Excellent SNR, up to 95 dB
