LT6018 33V, Ultralow Noise, Precision Op Amp Fea T Descrip T n Ultralow Voltage Noise The LT 6018 is a 33V precision operational amplifier n 30nV Noise: 0.1Hz to 10Hz with excellent noise performance. With 0.1Hz to 10Hz P-P n 1.2nV/Hz Typical at 1kHz noise of only 30nV , the LT6018 is an outstanding P-P n Maximum Offset Voltage: 50V choice for applications where 1/f noise impacts system n Maximum Offset Voltage Drift: 0.5V/C performance. The LT6018 has excellent DC performance n CMRR: 124dB (Minimum) with a maximum offset voltage of 50V and a maximum n A : 132dB (Minimum) offset voltage drift of 0.5V/C. The input offset voltage VOL n remains low over the entire common mode input range, Slew Rate: 30V/s n providing a minimum CMRR of 124dB. Open loop gain Gain-Bandwidth Product: 15MHz n is typically 142dB enabling the part to achieve linearity Wide Supply Range: 8V to 33V n better than 1ppm. The proprietary circuit topology of the Ultralow THD: 115dB at 1kHz n LT6018 provides excellent slew rate and settling time Unity Gain Stable without compromising noise or DC precision. n Low Power Shutdown: 6.2A 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 6.2A. A reference pin for the enable pin is also provided, which simplifies the interface between external a T circuitry and the LT6018. n ADC Driver Applications The LT6018 is available in 8-lead SO and 12-lead 4mm n Low Noise Precision Signal Processing 3mm DFN packages, both of which include an ex- n Multiplexed Applications posed pad to reduce thermal resistance. The LT6018 is n DAC Buffer specified over the 40C to 85C and 40C to 125C n Precision Data Acquisition temperature ranges. n Active Filters L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
