Description
Ground Reference For All Signals, 0 V.
Active Low Logic Output. RESET remains low while V CC is below the reset threshold or when MR is low;
RESET then remains low for at least 140 ms (at least 300 ms for the ADM811-3T) after V CC rises above the
reset threshold.
Active High Logic Output. RESET remains high while V CC is below the reset threshold or when MR is low;
RESET then remains high for 240 ms (typical) after V CC rises above the reset threshold.
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. A 0.1 μF decoupling capacitor between V CC and the
GND pin is recommended.
