TheLT1638/LT1639opampsoperateonallsingleandsplit  
supplies with a total voltage of 2.5V to 44V drawing only  
170μA of quiescent current per amplifier. These ampli-  
fiers are reverse battery protected and draw no current  
for reverse supply up to 18V.  
No Phase Reversal  
Available in 14-Lead SO, 8-Lead MSOP and DFN  
Packages  
The input range of the LT1638/LT1639 includes both sup-  
plies, and a unique feature of this device is its capability  
to operate over the top with either or both of its inputs  
+
APPLICATIONS  
above V . The inputs handle 44V, both differential and  
common mode, independent of supply voltage. The input  
stage incorporates phase reversal protection to prevent  
false outputs from occurring when the inputs are below  
the negative supply. Protective resistors are included in  
the input leads so that current does not become excessive  
when the inputs are forced below the negative supply.  
The LT1638/LT1639 can drive loads up to 25mA and still  
maintain rail-to-rail capability. The op amps are unity-gain  
stable and drive all capacitive loads up to 1000pF when  
optional output compensation is used.
