Linear Technology LT1678/LT1679 Datasheet
The LT1678 and LT1679 are dual/quad rail‑to‑rail operational amplifiers offering very low noise (3.9 nV/√Hz at 1 kHz) and high precision (typical 100 µV offset). They operate from a single supply of 2.7 V to 36 V and can swing within 170 mV of either rail.
Typical applications include strain‑gauge amplifiers, portable microphones, battery‑powered instrumentation, low‑noise signal processing, microvolt‑accuracy threshold detection, and infrared detectors. The devices are supplied in 8‑lead SO and 14‑lead SOQ packages with full matching specifications for instrumentation‑amplifier designs.
