Linear Technology LT1028/LT1128 Ultralow Noise Precision Op Amps Datasheet
The LT1028 and LT1128 are ultralow‑noise, precision op‑amps offering 0.85 nV/√Hz noise at 1 kHz (LT1028) and 1.0 nV/√Hz at 10 Hz. They combine high speed (gain‑bandwidth up to 50 MHz for LT1028, 13 MHz for LT1128) with low offset (40 µV max) and low input bias current (25 nA).
The document provides absolute maximum ratings, electrical characteristics, typical performance graphs, package dimensions, and recommended applications such as low‑noise synthesizers, audio, infrared detectors, and hydrophone amplifiers.
