LT1128: 13MHz Min. s Slew Rate LT1028: 11V/ µs Min. LT1128: 5V/ µs Min. s Offset Voltage: 40 µV Max. s Drift with Temperature: 0.8 µV/°C Max. s Voltage Gain: 7 Million Min. s Available in 8-Pin SO Package 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 µV/°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 50 Ω 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.
