LT9911 - (LT Series) Analog Optical Isolators

Download the LT9911 datasheet PDF. This datasheet also covers the LT9914 variant, as both devices belong to the same (lt series) analog optical isolators family and are provided as variant models within a single manufacturer datasheet.

General Description

PerkinElmer Optoelectronics has been a leading manufacturer of analog optical isolators (AOI) for over twenty years and makes a broad range of standard parts under its trademark VACTROL®.

There are many kinds of optical isolators, but the most common is the LED/phototransistor type.

Key Features

  • High input-to-output voltage isolation.
  • True resistance element output.
  • Single- or dual-element outputs available.
  • Low cost.
  • Suitable for AC or DC use.
  • Wide range of input-to-output characteristics.
  • Low drive current.
  • Low “on” resistance, high “off ” resistance.
  • Complete solid-state construction Typical.
