KM4270 - Rail-to-Rail I/O Amplifiers

Download the KM4270 datasheet PDF. This datasheet also covers the KM4170 variant, as both devices belong to the same rail-to-rail i/o amplifiers family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • at 2.7V.
  • 136µA supply current per amplifier.
  • 4.9MHz bandwidth.
  • Output swings to within 20mV of either rail.
  • Input voltage range exceeds the rail by >250mV.
  • 5.3V/µs slew rate.
  • 16mA output current.
  • 21nV/√Hz input voltage noise.
  • KM4170: directly replaces OPA340, OPA343, and TLV2461 in single supply.
