Linear Technology LT1169

The LT1169 achieves a new standard of excellence in noise performance for a dual JFET op amp. 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. When combined with a very low input capacitance (1.5pF) an extremely high input impedance results, making the LT1169 the first choice for amplifying low level signals from high impedance transducers.

The low input capacitance also assures high gain linearity when buffering AC signals from high impedance transducers. The LT1169 is unconditionally stable for gains of 1 or more, even with 1000pF capacitive loads.
