LT1128CN8#PBF

LT1128CN8#PBF is a (gain of +1 stable) ultralow noise precision high speed op-amp. It achieves a new standard of excellence in noise performance with 0.85nV/√Hz 1KHz noise, 1nV/√Hz 10Hz noise. This ultralow noise is combined with excellent high speed specifications, distortion-free output, and true precision parameters (0.1µV/°C drift, 10µV offset voltage, 30 million voltage gain). Although the LT1128 input stage operates at nearly 1mA of collector current to achieve low voltage noise, input bias current is only 25nA. The device's voltage noise is less than the noise of a 50 ohm resistor. Therefore, even in very low source impedance transducer or audio amplifier applications, it's contribution to total system noise will be negligible. Applications include low noise frequency synthesizers, high quality audio, infrared detectors, accelerometer and gyro amplifiers, 350 ohm bridge signal conditioning, magnetic search coil amplifiers, hydrophone amplifiers.
