36V Ultralow Noise Precision Op Amp Features 30nVP-P 0.1Hz to 10Hz Noise

Linear Technology introduces the LT6018, a precision op amp featuring 30nVP-P 0.1Hz to 10Hz noise and 50μV max input offset voltage. Designed especially for applications sensitive to low frequency noise, the LT6018 has a very low 1/f corner frequency of less than 1Hz. The low input offset voltage holds over temperature and input common mode range: TCVOS is 0.5μV/°C maximum and CMRR is 124dB minimum. Open loop gain is typically 142dB, enabling the device to achieve less than 1ppm nonlinearity.

The LT6018 has 15MHz gain-bandwidth product and employs slew enhancement circuitry to achieve up to 30V/µs slew rate. The part draws 7.2mA, which can be reduced during periods of non-use to 6.2μA using its shutdown pin.
The LT6018 is specified for operation from 8V to 33V supplies, for industrial (–40°C to 85°C) and extended (–40°C to 125°C) temperature ranges. It is available in SO-8E with exposed center pad for enhanced heat dissipation, and space-saving 4mm x 3mm DFN packages.
The LT6018 is priced starting at $3.25 each in 1,000 piece quantities. For more information, visit www.linear.com/product/LT6018.
