APPLICATIONS INFORMATION
Gain
The open-loop gain is almost independent of load when
the output is sourcing current. This optimizes performance
in single supply applications where the load is returned to
ground. The typical performance curve of open-loop gain
for various loads shows the details.
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 about 5μA and the output leakage
current is less than 1μA (V– ≤ VOUT ≤ V+). In normal opera-
tion, the SHDN pin can be tied to V– or left floating. See
the Typical Performance Characteristics curves, “Supply
Current vs Shutdown Voltage.”
