LT1028/LT1128

Ultra Low Noise Precision

High Speed Op Amps

DESCRIPTIO

EATURE

Voltage Noise

■

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.

Slew Rate

LT1028: 11V/µs Min.

LT1128: 5V/µs Min.

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.

Offset Voltage: 40µV Max.

Drift with Temperature: 0.8µV/°C Max.

Voltage Gain: 7 Million Min.
