FEATURES  
DESCRIPTION  
The LT ®1462 (dual) and LT1463 (quad) are the first  
micropower op amps (45µA max per amp) to offer  
picoampere input bias currents (1pA typ) and unity gain  
stability for capacitive loads up to 10nF. The output can  
swing a 10k load to within 1.5V of either supply, just like  
Input Bias Current:  
2pA Max (LT1462A)  
20pA Max (LT1462, LT1463)  
Supply Current per Amplifier: 45µA Max  
Unity-Gain Stable for C-LoadTM Up to 10nF  
Input Common Mode Range Includes Positive Rail  
Guaranteed Specs with ±5V, ±15V Supplies  
Gain Bandwidth Product: 175kHz Typ  
Slew Rate: 0.13V/µs Typ  
Guaranteed Matching Specifications  
Standard Pinout: SO-8, SO-14 Package  
op amps that require an order of magnitude more supply  
current. This unique combination of performance makes  
the LT1462/LT1463 ideal over a wide range of input and  
output impedances.  
In the design and testing of the LT1462/LT1463, particular  
emphasis has been placed on optimizing performance in  
thelowcostSO-8(dual)and14-leadSOpackage(quad)for  
±15V and ±5V supplies. The input common mode range  
includesthepositiverail. Slewrate(0.08V/µsmin)andgain
