FEATURES  
DESCRIPTIO  
The LT®1672/LT1673/LT1674 are ultralow power  
■
Gain of 5 Stable  
■
(IS ≤ 2µA) decompensated (AV ≥ 5) op amps with preci-  
sion specifications. The extremely low supply current is  
combined with excellent amplifier specifications: input  
offset voltage is 375µV maximum with a typical drift of  
only 0.4µV/°C, input offset current is 100pA maximum. A  
minimumopen-loopgain(AVOL)of100V/mVensuresthat  
gain errors are small. The devices’ characteristics change  
little over the supply range of 2.2V to ±15V. Supply  
rejection is 90dB and the common mode rejection ratio is  
90dB. Operationisspecifiedfor3V, 5Vand±15Vsupplies.  
Reverse battery protection (–18V min) and inputs that  
operate above the positive supply make the LT1672/  
LT1673/LT1674 easy to use in harsh environments.

Low Input Bias Current: 250pA  
Low Input Offset Current: 20pA  
High AVOL: 100V/mV Minimum Driving 100kΩ Load  
Output Sources and Sinks 500µA Load Current  
Reverse Battery Protected to 18V  
U
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. For  
unity gain stable versions of these amplifiers, see the  
LT1494/LT1495/LT1496.
