LT1113 Dual Low Noise, Precision, JFET Input Op Amps

Most H (Metal Can), J (Ceramic), and K (Metal Can) Packages from linear Technology Are Now Obsolete

The LT®1113 achieves a new standard of excellence in noise performance for a dual JFET op amp. The 4.5nV/Rt.Hz 1kHz noise combined with low current noise and picoampere bias currents makes the LT1113 an ideal choice for amplifying low level signals from high impedance capacitive transducers.

The LT1113 is unconditionally stable for gains of 1 or more, even with load capacitances up to 1000pF. Other key features are 0.4mV VOS and a voltage gain of 4 million. Each individual amplifier is 100% tested for voltage noise, slew rate and gain bandwidth.

The design of the LT1113 has been optimized to achieve true precision performance with an industry standard pinout in the S0-8 package. A set of specifications are provided for ±5V supplies and a full set of matching specifications are provided to facilitate the use of the LT1113 in matching dependent applications such as instrumentation amplifier front ends
