Analog Devices ADM691A/ADM693A/ADM800L/M Datasheet
The ADM691A, ADM693A, ADM800L, and ADM800M are microprocessor supervisory circuits that offer power‑on reset, battery backup switching, watchdog timer, and power‑fail detection. They are supplied in 16‑pin DIP, SO, and for ADM691A also a space‑saving TSSOP package.
The document lists electrical specifications such as operating voltage range, supply current, reset thresholds, and watchdog timing, and includes pin‑out tables, typical performance curves, and ordering information.
