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 160
μ
A 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.
The KM4X70 family of amplifiers offer high bipolar
performance at a low CMOS prices. They offer superior
dynamic performance with 4.9MHz small signal bandwidths
and 5.3V/
μ
s slew rates. The combination of low power, high
bandwidth, and rail-to-rail performance make the KM4X70
amplifiers well suited for battery-powered communication/
computing systems.
