Low Input Offset Voltage: 500µV Max  
The LT 1490A/LT1491A are dual and quad op amps with a  
Output Swings to 10mV Max from V–  
Rail-to-Rail Input and Output  
■
lowinputoffsetvoltageof500µVmax.TheLT1490A/LT1491A  
operate on all single and split supplies with a total voltage of  
2V to 44V, drawing only 40µA of quiescent current per  
amplifier. These amplifiers are reverse supply protected;  
they draw virtually no current for reverse supply up to 18V.  
The input range of the LT1490A/LT1491A includes both  
suppliesandtheoutputswingstobothsupplies. Unlikemost  
micropower op amps, the LT1490A/LT1491A can drive  
heavy loads; their rail-to-rail outputs drive 20mA. The  
LT1490A/LT1491A are unity-gain stable and drive all capaci-  
tive loads up to 10,000pF when optional 0.22µF and 150Ω  
compensation is used.

The LT1490A/LT1491A have a unique input stage that oper-  
ates and remains high impedance when above the positive  
supply. The inputs take 44V both differential and common  
mode even when operating on a 3V supply. Built-in resistors  
protect the inputs for faults below the negative supply up to  
15V. There is no phase reversal of the output for inputs 15V
