LT1113CN8#PBF

LT1113 is a dual, low noise, precision, JFET input op-amp. This achieves a new standard of excellence in noise performance for a dual JFET op-amp. The 4.5nV/√Hz 1KHz noise combined with low current noise and picoampere bias currents makes an ideal choice for amplifying low level signals from high impedance capacitive transducers. Each individual amplifier is 100% tested for voltage noise, slew rate and gain bandwidth. Design of the LT1113 has been optimized to achieve true precision performance with an industry standard pinout. A set of specification is provided for ±5V supplies and a full set of matching specifications are provided to facilitate the use of the matching dependent applications such as instrumentation amplifier front ends. Applications include photocurrent amplifiers, hydrophone amplifiers, high sensitivity piezoelectric accelerometers, low voltage and current noise instrumentation, amplifier front ends, two and three op-amp instrumentation amplifiers, active filters.
