Input and Output  
Op Amp in SOT-23  
FEATURES  
DESCRIPTION  
TheLT®1797isaunity-gainstable10MHzopampavailable  
in the small SOT-23 package that operates on all single  
and split supplies with a total voltage of 2.7V to 12V. The  
amplifier draws 1mA of quiescent current and has a slew  
rate of 2.25V/μs.

Low Input Offset Voltage: 1.5mV Max  
The input common mode range of the LT1797 includes  
both rails, making it ideal for current sensing applications.  
The input stage incorporates phase reversal protection  
to prevent false outputs from occurring when the inputs  
are driven beyond the supplies. Protective resistors are  
includedintheinputleadssothatcurrentdoesnotbecome  
excessive when the inputs are forced above or below the  
supplies.
