Ultralow Voltage Noise
The LT®6018 is a 33V precision operational amplifier n
30nVP-P Noise: 0.1Hz to 10Hz
with excellent noise performance. With 0.1Hz to 10Hz n
1.2nV/√
Hz
Typical at 1kHz
noise of only 30nVP-P, the LT6018 is an outstanding n
Maximum Offset Voltage: 50μV
choice for applications where 1/f noise impacts system n
Maximum Offset Voltage Drift: 0.5μV/°C
performance. The LT6018 has excellent DC performance n
CMRR: 124dB (Minimum)
with a maximum offset voltage of 50µV and a maximum n AVOL: 132dB (Minimum) offset voltage drift of 0.5µV/°C. The input offset voltage n Slew Rate: 30V/μs remains low over the entire common mode input range, n Gain-Bandwidth Product: 15MHz providing a minimum CMRR of 124dB. Open loop gain n Wide Supply Range: 8V to 33V is typically 142dB enabling the part to achieve linearity n Ultralow THD: –115dB at 1kHz better than 1ppm. The proprietary circuit topology of the n Unity Gain Stable LT6018 provides excellent slew rate and settling time n Low Power Shutdown: 6.2µA without compromising noise or DC precision. n SO-8E and 4mm × 3mm 12-Lead DFN Packages An enable pin allows the LT6018 to be put in a low power n 4.5kV HBM and 2kV CDM Tolerant 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
