LT6018 Low Noise, High CMRR Instrumentation Amplifier

Low Noise, High CMRR Instrumentation Amplifier

The LT®6018 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.
