LT1028CN8#PBF Datasheet PDF - Linear Technology

The LT1028CN8#PBF is an ultralow noise precision high speed Operational Amplifier achieves a new standard of excellence in noise performance with 0.85nV/√Hz 1kHz noise, 1.0nV/√Hz 10Hz noise. This ultralow noise is combined with excellent high speed specifications (gain-bandwidth product is 75MHz), distortion-free output and true precision parameters (0.1µV/°C drift, 10µV offset voltage, 30million voltage gain). Although the input stage operates at nearly 1mA of collector current to achieve low voltage noise, input bias current is only 25nA. The LT1028"s voltage noise is less than the noise of a 50R resistor. Therefore, even in very low source impedance transducer or audio amplifier applications, the LT1028"s contribution to total system noise will be negligible.
