### 4. Functionality

Operation Principle:
The ACL‑8312 performs analog‑to‑digital conversion using a 12‑bit successive‑approximation ADC. Input signals are multiplexed across 16 SE or 8 DI channels, amplified by a programmable gain amplifier, and digitized at up to 100 kS/s. Data is buffered in a 1 K FIFO and transferred to system memory via polling, interrupt, or DMA.

Use Cases:
- Industrial process monitoring and control
- Laboratory data logging and signal analysis
- Energy management and automation
- Product testing and quality assurance
- Security and annunciation systems
- Pulse width and frequency measurement

Compatibility:
ISA‑bus PCs running DOS, Windows 95/98/NT. Supported by ADLINK’s NuDAQ software suite, C/C++ libraries, and LabVIEW drivers.
