PIN FUNCTIONS –IN:
Inverting Input of the Amplifier. The voltage range of as the voltage difference between V+ and V– is between this pin is from V– to V+ –0.5V. 3.1V and 5.25V. If it is not connected to ground, bypass
+IN:
Non-Inverting Input. The voltage range of this pin is it to ground with a capacitor of 0.1µF as close to the pin from V– to V+ –0.5V. as possible.
V+:
Positive Power Supply. Total supply (V+ – V–) voltage
SHDN, SDA, SDB:
Active Low op amp shutdown, threshold is from 3.1V to 5.25V. Split supplies are possible as long is 0.75V above the negative supply, V–. If left unconnected, as the total voltage between V+ and V– is between 3.1V the amplifier is enabled. and 5.25V. A bypass capacitor of 0.1µF should be used
OUT:
Amplifier Output. between V+ to ground as close to the pin as possible.
NC:
Not connected. May be used to create a guard ring
V–:
Negative Power Supply. Normally tied to ground, it around the input to guard against board leakage currents. can also be tied to a voltage other than ground as long See Applications Information section for more details. 626810f 10 For more information www.linear.com/LTC6268-10 Document Outline Features Applications Typical Application Description Absolute Maximum Ratings Pin Configuration Order Information 5.0V Electrical Characteristics Typical Performance Characteristics Pin Functions Simplified Schematic Operation Applications Information Package Description Typical Application Related Parts
