The LT6018 is a 33V precision operational amplifier with excellent noise performance. With 0.1Hz to 10Hz noise of only 30nV_P-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.

Tools & Simulations

LTspice 2

Models for the following parts are available in LTspice:

LT6018

Analog Photodiode Wizard

Use Photodiode Wizard to design a transimpedance amplifier circuit to interface with a photodiode. Select a photodiode from the library included in the tool, or enter custom photodiode specifications. Quickly observe tradeoffs between Bandwidth, Peaking (Q), and ENOB/SNR. Modify circuit parameters, and immediately see results in plots for pulse response, frequency response, and noise gain.

Open Tool

Analog Filter Wizard

Use the Analog Filter Wizard to design low-pass, high-pass, or band-pass filters with actual op amps in minutes. As you progress through the design process, you can observe the characteristics of your filter design from ideal specifications to real world circuit behavior. Quickly evaluate the tradeoffs in op amp specifications - including gain-bandwidth, noise, and supply current – to determine the best filter design for your requirements.
