The LT1800 is a low power, high speed, rail-to-rail input and output operational amplifier with excellent DC perfor- mance.
The LT1800 is a low‑power, high‑speed operational amplifier that features rail‑to‑rail input and output, a gain‑bandwidth product of 80 MHz, and a slew rate of 25 V/µs. It operates from 2.3 V to 12.6 V supply voltage and maintains performance over a temperature range of –40 °C to 85 °C.
Typical applications include low‑voltage, high‑frequency signal processing, driving A/D converters, rail‑to‑rail buffer amplifiers, active filters, and video line drivers. The device is offered in 8‑pin SO and 5‑pin ThinSOT (SOT‑23) packages for flexible board layout.
