The LT
®
1102 is the first fast FET input instrumentation
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, 180μV 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.
