Product Details

The LT6018 is a 33V precision operational amplifier with excellent noise performance. With 0.1Hz to 10Hz noise of only 30nVP-P, the LT6018 is an outstanding choice for applications where 1/f noise impacts system performance. The LT6018 has excellent DC performance with a maximum offset voltage of 50μV and a maximum offset voltage drift of 0.5μV/°C. The input offset voltage remains low over the entire common mode input range, providing a minimum CMRR of 124dB. Open loop gain is typically 142dB enabling the part to achieve linearity better than 1ppm. The proprietary circuit topology of the LT6018 provides excellent slew rate and settling time without compromising noise or DC precision.

An enable pin allows the LT6018 to be put in a low power shutdown mode, reducing the typical supply current to only 6.2μA. A reference pin for the enable pin is also provided, which simplifies the interface between external circuitry and the LT6018.

The LT6018 is available in 8-lead SO and 12-lead 4mm × 3mm DFN packages, both of which include an exposed pad to reduce thermal resistance. The LT6018 is specified over the –40°C to 85°C and –40°C to 125°C temperature ranges.
