### 4. Functionality and Applications

Operating Principle:
The AI‑1616L‑LPE converts analog voltages from external sensors or instruments into 16‑bit digital data via an onboard A/D converter. Sampling is controlled by internal or external clocks and can be triggered by software or external TTL signals. Data are temporarily stored in the 1 k‑word buffer, then transferred to host memory through the PCI Express bus.

Typical Use Cases:
- Industrial process monitoring and control
- Laboratory data acquisition and waveform logging
- Sensor signal digitization (temperature, pressure, vibration)
- Automated test systems requiring multi‑channel analog input
- Integration with MATLAB or LabVIEW for scientific analysis

Compatibility:
Fully compatible with CONTEC’s API‑AIO driver family and legacy PCI ADI16‑16(LPCI)L pinout. Works with Windows (32/64‑bit) and Linux kernels via supplied drivers.
