DAQ-100: Nano-Scale High-Precision Multi-Channel Data Acquisition and Control Card
Product Description
1. Product Overview
The DAQ-100 is a high-performance data acquisition and conversion expansion card specifically designed for nano-scale laser processing, micro-displacement precision control, and high-sensitivity photoelectric detection. Serving as the core signal hub of a micro/nano positioning system, the DAQ-100 integrates multi-channel, high-resolution analog-to-digital conversion (ADC) and high-dynamic-range digital-to-analog conversion (DAC) modules on a single platform.
Through an industrial-grade HSMC interface, the DAQ-100 seamlessly interfaces with ZYNQ FPGA–based controllers and other FPGA host platforms, enabling full closed-loop control from optical signal acquisition to precision piezoelectric actuator (PZT) drive.
2. Key Advantages
Ultra-Low-Noise Power Architecture
The system supports ±24 V industrial supply input with wide dynamic range. An internal ultra-low-noise, high-precision linear regulation architecture generates seven independent precision power rails (+12 V, −12 V, +5 V, −5 V, +3.3 V, −3.3 V, +2.5 V, etc.). This architecture fundamentally suppresses ripple and switching noise, ensuring signal integrity at full 16-bit resolution.
High-Dynamic, Fast-Response Drive Capability
Equipped with four 16-bit high-precision DAC channels operating at up to 1 MSPS, the DAQ-100 is optimized for piezoelectric actuator (PZT) control. It delivers excellent voltage linearity and fast transient response, enabling real-time nano-scale displacement compensation.
Flexible Multi-Range Signal Acquisition
Multiple programmable analog input ranges (0–5 V, 0–10 V, −10–0 V) support a wide variety of sensors, including quadrant photodiodes (QPDs) and photodiodes. With parallel multi-channel sampling, the system enables real-time monitoring of reflected intensity, transmitted intensity, and laser power normalization signals.
Industrial-Grade Physical Connectivity
Professional LEMO connectors, along with SMB / SMA / SMC RF connectors, are employed for all critical analog interfaces. This industrial-grade interconnection scheme minimizes signal loss and significantly enhances electromagnetic compatibility (EMC) in electrically noisy environments.
