The LT

amplifier offered in the low cost, space saving 8-pin

packages. Fixed gains of 10 and 100 are provided with

excellent gain accuracy (0.01%) and non-linearity (3ppm).

No external gain setting resistor is required.

Slew rate, settling time, gain-bandwidth product,

overdrive recovery time are all improved compared to

competitive high speed instrumentation amplifiers.

Industry best speed performance is combined with

impressive precision specifications: less than 10pA input

bias and offset currents, 180

μV offset voltage. Unlike

other FET input instrumentation amplifiers, on the LT1102

there is no output offset voltage contribution to total error,

and input bias currents do not double with every 10

°C rise

in temperature. Indeed, at 70

°C ambient temperature the

input bias current is only 40pA.
