LT1101 Datasheet PDF

●The LT1101CN8#PBF is a precision micropower single supply Instrumentation Amplifier for differential voltage-to-current converter. The amplifier is completely self-contained, no external gain setting resistor is required. The amplifier combines its micropower operation (75µA supply current) with a gain error of 0.008%, gain linearity of 3ppm, gain drift of 1ppm/°C. The output is guaranteed to drive a 2k load to ±10V with excellent gain accuracy. Other precision specifications are also outstanding - 50µV input offset voltage, 130pA input offset current and low drift (0.4µV/°C and 0.7pA/°C). In addition, unlike other instrumentation amplifiers, there is no output offset voltage contribution to total error. A full set of specifications are provided with ±15V dual supplies and for single 5V supply operation. The amplifier can be operated from a single lithium cell or two Ni-Cad batteries. Battery voltage can drop as low as 1.8V, yet the LT1101 still maintains its gain accuracy.
