DESCRIPTION

The of +1 stable) achieve 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 for LT1028, 20MHz for LT1128), distortion-free output, and true precision parameters (0.1V/C drift, 10V offset voltage, 30 million voltage gain). Although the LT1028/ LT1128 input stage operates at nearly 1mA of collector current to achieve low voltage noise, input bias current is only 25nA. The LT1028/LT1128's voltage noise is less than the noise a 50 resistor. Therefore, even in very low source impedance transducer or audio amplifier applications, the LT1028/LT1128's contribution to total system noise will be negligible.
