1.5µA Max, Single, Dual  
and Quad Over-The-Top Precision  
Rail-to-Rail Input and Output Op Amps

FEATURES  
DESCRIPTIO  
The LT®1494/LT1495/LT1496 are the lowest power  
(IS 1.5µA) op amps with precision specifications. The  
extremely low supply current is combined with excellent  
Low Supply Current: 1.5µA Max  
Rail-to-Rail Input and Output  
Low Offset Voltage: 375µV Max  
amplifier specifications: input offset voltage is 375µV  
maximum with a typical drift of only 0.4µV/°C, input offset  
current is 100pA maximum. A minimum open-loop gain  
(AVOL) of 100V/mV ensures that gain errors are small. The  
device characteristics change little over the supply range  
of2.2Vto±15V. Supplyrejectionis90dBandthecommon  
moderejectionratiois90dB. Operationisspecifiedfor3V,  
5V and ±15V supplies. Reverse battery protection  
(–18V min) and inputs that operate above the positive  
supply make the LT1494/LT1495/LT1496 easy to use in  
harsh environments.  
Operating Temperature Range: 40°C to 125°C  
Over-The-TopTM Inputs Operate Above V+  
Wide Supply Range: 2.2V to 36V  
Single Supply Input Range: 0.3V to 36V  
Low Input Bias Current: 250pA  
Low Input Offset Current: 20pA  
High AVOL: 100V/mV Minimum Driving 100kLoad  
Output Sources and Sinks 500µA Load Current  
Reverse Battery Protected to 18V  
U
APPLICATIO S  
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.

The LT1494 is available in the 8-Pin MSOP, PDIP and SO  
packages.The LT1495 is available in plastic 8-Pin PDIP  
and SO packages with the standard dual op amp pinout.  
The LT1496 is available in 14-Pin SO and PDIP packages.
