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 (0.1

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 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.
