- Externally‑Triggered Output: Conversion synchronized to external TTL trigger or clock signals for deterministic timing.
- Buffered Output: Data streamed from on‑board 1 k‑word buffer, allowing continuous waveform generation independent of CPU load.
- Synchronous Operation: Analog output can be synchronized with digital I/O or counter events for coordinated control.

Typical Applications
- Process control and analog actuator driving
- Signal generation and waveform output
- Data acquisition systems requiring analog stimulus
- Laboratory automation and test benches
- Embedded control in industrial PCs or compact measurement systems
