The LT

1494/LT1495/LT1496 are the lowest power

≤

1.5µA) op amps with precision 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 minimum open-loop gain

VOL

) of 100V/mV ensures that gain errors are small. The

device characteristics 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 LT1494/LT1495/LT1496 easy to use in

harsh environments.

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 4µV

P-P

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.
