FEATURES  
DESCRIPTIO  
Operates with Inputs Above V+  
The LT®1782 is a 200kHz op amp available in the small  
SOT-23 package that operates on all single and split  
supplies with a total voltage of 2.5V to 18V. The amplifier  
drawslessthan55µAofquiescentcurrentandhasreverse  
battery protection, drawing negligible current for reverse  
supply voltages up to 18V.  
Rail-to-Rail Input and Output  
Micropower: 55µA Supply Current Max  
Operating Temperature Range: 40°C to 125°C  
Low Profile (1mm) ThinSOTTM Package  
Low Input Offset Voltage: 800µV Max  
Single Supply Input Range: 0V to 18V  
High Output Current: 18mA Min  
Specified on 3V, 5V and ±5V Supplies  
Output Shutdown on 6-Lead Version  
Reverse Battery Protection to 18V  
High Voltage Gain: 1500V/mV  
Gain Bandwidth Product: 200kHz  
Slew Rate: 0.07V/µs  
The input range of the LT1782 includes ground, and a  
unique feature of this device is its Over-The-TopTM opera-  
tion capability with either or both of its inputs above the  
positive rail. The inputs handle 18V both differential and  
common mode, independent of supply voltage. The input  
stage incorporates phase reversal protection to prevent  
false outputs from occurring even when the inputs are 9V  
below the negative supply.  
U
The LT1782 can drive loads up to 18mA and still maintain  
rail-to-rail capability. A shutdown feature on the 6-lead  
version can disable the part, making the output high  
impedance and reducing quiescent current to 5µA. The  
LT1782 op amp is available in the 5- and 6-lead  
SOT-23packages.Forapplicationsrequiringhigherspeed,
