Description
Ground Reference For All Signals, 0 V.
Active Low Logic Output. RESET remains low while V
RESET then remains low for at least 140 ms (at least 300 ms for the ADM811-3T) after V
reset threshold.
Active High Logic Output. RESET remains high while V
RESET then remains high for 240 ms (typical) after V
Manual Reset. This active low debounced input ignores input pulses of 100 ns or less (typical) and is
guaranteed to accept input pulses of greater than 10 μs. Leave floating when not used.
Monitored Supply Voltage of 2.5 V, 3 V, 3.3 V, or 5 V.
