LT1169CN8#PBF

LT1169 dual low noise picoampere bias current JFET input operational amplifier achieves a new standard of excellence in noise performance. For the first time low voltage noise (6nV/√Hz) is simultaneously offered with extremely low current noise (1fA/√Hz), providing the lowest total noise for high impedance transducer applications. Unlike most JFET op amps, the very low input bias current (5pA typical) is maintained over the entire common mode range which results in an extremely high input resistance (1013ohm). This low input capacitance also assures high gain linearity when buffering AC signals from high impedance transducers. Typical applications are photocurrent amplifiers, hydrophone amplifiers, high sensitivity piezoelectric accelerometers, low voltage and current noise instrumentation amplifier front ends, 2 and 3 Op Amp instrumentation amplifiers, active filters.
