"The Le87411 is a single channel differential amplifier with very low power dissipation. The Le87411 contains a pair of wideband amplifiers designed with Microsemi's HV15 Bipolar SOI process for low power consumption. The line driver gain is fixed internally. The amplifiers are powered from a single supply. The device can be programmed to one of three preset bias levels or to impedance controlled Disable or Standby states. The control pins respond to input levels that can be generated with a standard tri-state GPIO."
