The LT1028(gain of -1 stable)/LT1128(gain of +1 stable achieve a new standard of excellence in noise performance with 0.85nV/Hz 1kHz noise, 1.0nV/Hz 10Hz noise. This ultra low 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/ 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 nois of a 50resistor. Therefore, even in very low source impedance transducer or audio amplifier applications, the LT1028/LT1128°Os contribution to total system noise wil be negligible.
