KM4170 Datasheet (Fairchild Semiconductor) - Rail-to-Rail I/O Amplifiers

KM4170, Rail-to-Rail I/O Amplifiers

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
