The LT1800 is a low power, high speed, rail-to-rail input and output operational amplifier with excellent DC performance.
The LT1800 is a low‑power, high‑speed operational amplifier with rail‑to‑rail input and output capability. It offers a gain‑bandwidth product of 80 MHz, a slew rate of 25 V/µs, and low quiescent current (2 mA max), making it suitable for battery‑powered and high‑frequency designs.
Typical applications include low‑voltage high‑frequency signal processing, driving A/D converters, rail‑to‑rail buffer stages, active filters, video line drivers, and precision amplification for laser drivers. The device is offered in 8‑pin SO and 5‑pin ThinSOT packages and operates from 2.3 V to 12.6 V supply voltages.
