Ultralow Noise Precision
High Speed Op Amps
The LT1028(gain of –1 stable)/LT1128(gain of +1 stable)
achieveanewstandardofexcellenceinnoiseperformance
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
of a 50Ω 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.
