Linear Technology introduces the LT6018, a precision op amp featuring 30nVP-P 0.1Hz to 10Hz noise and 50µV maximum 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/degree 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 to 85 degrees C) and extended (–40 to 125 degrees 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.
