SIMPLIFIED SCHEMATIC

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.”
