KM4470 Overview
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). The input voltage range exceeds the negative and positive rails.
