The LT1815/LT1816/LT1817 are low power, high speed, very high slew rate operational amplifiers with excellent DC performance. The LT1815/LT1816/LT1817 feature higher bandwidth and slew rate, much lower input offset voltage and lower noise and distortion than other devices with comparable supply current. A programmable current option (LT1815 and LT1816A) allows power savings and flexibility by operating at reduced supply current and speed. The circuit topology is a voltage feedback amplifier with the slewing characteristics of a current feedback amplifier.
The LT1815, LT1816 and LT1817 are low‑power, high‑speed operational amplifiers with a 1500 V/µs slew rate, 220 MHz gain‑bandwidth product and programmable supply current options. They are offered in ultra‑small SOT‑23, MSOP, SSOP and lead‑less DFN packages for use in wideband amplifiers, active filters, video/RF amplification, communication receivers and data‑acquisition systems.
The document provides absolute maximum ratings, detailed electrical characteristics, typical performance curves and package dimensions. It also includes ordering information for the various package types and typical application circuits such as band‑pass filters with independently settable gain and Q.
