pin Functions
–IN: Inverting Input of the Amplifier. Voltage range of this
pin can go from V– 0.1V to V+ + 0.1V.
+IN: Non-Inverting Input of Amplifier. This pin has the
same voltage range as –IN.
V+: Positive Power Supply. Typically the voltage is from
1.8V to 5.25V. Split supplies are possible as long as the
voltage between V+ and Vis between 1.8V and 5.25V. A
bypass capacitor of 0.1F as close to the part as possible
should be used between power supply pins or between
supply pins and ground.
V: Negative Power Supply. It is normally tied to ground.
It can also be tied to a voltage other than ground as long
as the voltage between V+ and Vis from 1.8V to 5.25V.
If it is not connected to ground, bypass it with a capacitor
of 0.1F as close to the part as possible.
SHDN: Active Low Shutdown. Shutdown threshold is 0.6V
above negative rail. If left unconnected, the amplifier will
be on.
OUT:AmplifierOutput.Thevoltagerangeextendstowithin
millivolts of each supply rail.
