KM4470 - Low Cost/ +2.7V & +5V/ Rail-to-Rail I/O Amplifiers

General Description

The KM4170 (single), KM4270 (dual), and KM4470 (quad) are ultra-low cost, low power, voltage feedback amplifiers.

At 5V, the KM4X70 family uses only 160µA of supply current per amplifier and are designed to operate from a supply range of 2.5V to 5.5V (±1.25 to ±2.75).

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.
