LT1496

The LT^®1494/LT1495/LT1496 are the lowest power(IS 1.5µA) op amps with precision specifications. Theextremely low supply current is combined with excellentamplifier specifications: input offset voltage is 375µVmaximum with a typical drift of only 0.4µV/°C, input offsetcurrent is 100pA maximum. A minimum open-loop gain(AVOL) of 100V/mV ensures that gain errors are small. Thedevice characteristics change little over the supply rangeof 2.2V to ±15V. Supply rejection is 90dB and the commonmode rejection ratio is 90dB. Operation is specified for 3V,5V and  ±15V supplies. Reverse battery protection(18V␣ min) and inputs that operate above the positivesupply make the LT1494/LT1495/LT1496 easy to use inharsh environments.

The low bias currents and offset current of the amplifierpermit the use of megohm level source resistors withoutintroducing significant errors. Voltage noise at 4µVP-P isremarkably low considering the low supply current.

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

The LT1496 is available in 14-Pin SO and PDIP packages.
