LT1028/LT1128
Ultralow Noise Precision
High Speed Op Amps
FEATURES DESCRIPTION Voltage Noise 1.1nV/√Hz Max at 1kHz 0.85nV/√Hz Typ at 1kHz 1.0nV/√Hz Typ at 10Hz 35nVP-P Typ, 0.1Hz to 10Hz
n Voltage and Current Noise 100% Tested
n Gain-Bandwidth Product LT1028: 50MHz Min LT1128: 13MHz Mi Slew Rate LT1028: 11V/µs Min LT1128: 5V/µs Mi Offset Voltage: 40µV Max
n Drift with Temperature: 0.8µV/°C Max
n Voltage Gain: 7 Million Mi Available in 8-Lead SO Package The LT®1028(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
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 (0.1µV/°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. APPLICATIONS L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear

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. Low Noise Frequency Synthesizers High Quality Audio …
