Overview

  • 100% Tested Low Voltage Noise: 6nV/√Hz Max
  • S8 Package Standard Pinout
  • Voltage Gain: 1.2 Million Min
  • Offset Voltage: 1.5mV Max
  • Offset Voltage Drift: 15µV/°C Max
  • Input Bias Current, Warmed Up 450pA Max
  • Gain-Bandwidth Product: 5.6MHz Typ
  • Guaranteed Specifications with ±5V Supplies
  • Guaranteed Matching Specifications

The LT1113 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 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.
