LT1102CN8#PBF

LT1102 is a first fast FET input instrumentation amplifier. Fixed gains of 10 and 100 are provided with excellent gain accuracy (0.01%) and non-linearity (3ppm). 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 device there is no output offset voltage contribution to total error, and input bias currents do not double with every 10°C rise in temperature. It is used in applications such as fast settling analogue signal processing, multiplexed input data acquisition systems, high source impedance signal amplification from high resistance bridges, capacitance sensors, photodetector sensors, bridge amplifier with <lt/> 1Hz lowpass filtering.
