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 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.

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.

Applications

  • Low Noise Frequency Synthesizers
  • High Quality Audio
  • Infrared Detectors
  • Accelerometer and Gyro Amplifiers
  • 350 ohms Bridge Signal Conditioning
  • Magnetic Search Coil Amplifiers
  • Hydrophone Amplifiers
