The LT1028(gain of –1 stable)/LT1128(gain of +1 stable)  
achieveanewstandardofexcellenceinnoiseperformance  
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 (0.1µV/°C drift, 10µV 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  
of a 50resistor. Therefore, even in very low source  
impedance transducer or audio amplifier applications, the  
LT1028/LT1128’s contribution to total system noise will  
be negligible.
