FEATURES

The LT

amps with precision specifications. The extremely low

supply current is combined with excellent amplifier speci-

fications: input offset voltage is 375

µV maximum with a

typical drift of only 0.4

µV/°C, input offset current is 100pA

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.

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 4

remarkably low considering the low supply current.

The LT1495 is available in plastic 8-pin PDIP and SO-8

packages with the standard dual op amp pinout. The

LT1496 is available in 14-pin SO and PDIP packages.
