FEATURES  
DESCRIPTION  
TheLT®1495/LT1496arethelowestpower(IS 1.5µA)op  
amps with precision specifications. The extremely low  
supply current is combined with excellent amplifier speci-  
fications: input offset voltage is 375µV maximum with a  
typical drift of only 0.4µV/°C, input offset current is 100pA  
maximum.Aminimumopen-loopgain(AVOL)of100V/mV  
ensures that gain errors are small. The device character-  
istics change little over the supply range of 2.2V to ±15V.  
Supply rejection is 90dB and the common mode rejection  
ratio is 90dB. Operation is specified for 3V, 5V and ±15V  
supplies. Reverse battery protection (–18V min) and  
inputs that operate above the positive supply make the  
LT1495/LT1496 easy to use in harsh environments.

APPLICATIONS  
The low bias currents and offset current of the amplifier  
permit the use of megohm level source resistors without  
introducing significant errors. Voltage noise at 4µVP-P is  
remarkably low considering the low supply current.
