Op amp is for noise-sensitive applications

A precision op amp from Linear Technology features 30nVP-P 0.1Hz to 10Hz noise and 50microV maximum input offset voltage. The LT6018 is designed for applications sensitive to low frequency noise, with a low 1/f corner frequency of less than 1Hz. The low input offset voltage holds over temperature and input common mode range. TCVOS is 0.5microV/°C maximum and CMRR is 124dB minimum. Open loop gain is typically 142dB, enabling the device to achieve less than 1ppm non-linearity.

The op amp has 15MHz gain-bandwidth and employs slew enhancement circuitry to achieve up to 30V/micro sec slew rate. The part draws 7.2mA, which can be reduced during periods of non-use to 6.2microA using its shutdown pin.

The op amp is specified for operation from 8.0 to 33V supplies, for industrial (-40 to +85 degree C) and extended (-40 to +125 degree C) temperature ranges. It is available in SO-8E with exposed centre pad for enhanced heat dissipation, and a compact 4.0 x 3.0mm DFN packages.
