FEATURES  
DESCRIPTIO  
The LT®1797 is a unity-gain stable 10MHz op amp avail-  
able in the small SOT-23 package that operates on all  
singleandsplitsupplieswithatotalvoltageof2.7Vto12V.  
The amplifier draws 1mA of quiescent current and has a  
slew rate of 2.25V/µs.  
Rail-to-Rail Input and Output  
Small SOT-23 Package  
Gain Bandwidth Product: 10MHz  
–40°C to 85°C Operation  
Slew Rate: 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 in-  
cluded in the input leads so that current does not become  
excessive when the inputs are forced above or below the  
supplies.  
The output of the LT1797 can swing to within 50mV of V+  
and 8mV of Vwithout drawing excess current in either  
condition. The amplifier can drive loads up to 25mA and  
still maintain rail-to-rail capability.  
High Output Current: 25mA Min  
Specified on 3V, 5V and ±5V Supplies  
High Voltage Gain: 1000V/mV 10k Load  
High CMRR: 88dB Min  
High PSRR: 80dB Min  
Input Bias Current: 300nA Max  
Input Offset CurrUent: 25nA Max  
APPLICATIO S  
Portable Instrumentation  
Rail-to-Rail Buffer Amplifiers  
Low Voltage Signal Processing
