APPLICATIONS INFORMATION
Shutdown
The 6-lead part includes a shutdown feature that disables
the part, reducing quiescent current and making the output
high impedance. The part can be shut down by bringing
the SHDN pin 1.2V or more above V
–
. When shut down,
the supply current is less than 1µA (V
–
≤ V
OUT
≤ V
+
). In
normal operation, the SHDN pin can be tied to V
–
or left
fl oating. See Typical Performance Characteristics curve,
“Supply Current vs SHDN pin Voltage.”
