KM4170, KM4270, KM4470
Low Cost, +2.7V & +5V, Rail-to-Rail I/O Amplifiers
Features at 2.7V
Description
• 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
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.
• 16mA output current
• 21nV/√Hz input voltage noise
• KM4170:
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/µs 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.

Overdrive Recovery
Application Information
Overdrive of an amplifier occurs when the output and/or input
ranges are exceeded. The recovery time varies based on
whether the input or output is overdriven and by how much
the ranges are exceeded. The KM4X70 will typically recover
in less than 50ns from an overdrive condition. Figure 3 shows
the KM4X70 amplifier family in an overdriven condition.
General Description
The KM4X70 family of amplifiers are single supply, general
purpose, voltage-feedback amplifiers. They are fabricated on
a complimentary bipolar process, feature a rail-to-rail input
and output, and are unity gain stable.
The typical non-inverting circuit schematic is shown in Figure 1.

Exceeding these values will not cause phase reversal. However,
if the input voltage exceeds the rails by more than 0.5V, the
input ESD devices will begin to conduct. The output will

exceeded, externally limit the input current to 5mA as

10kΩ
Figure 2: Circuit for Input Current Protection
Driving a capacitive load introduces phase-lag into the output
signal, which reduces phase margin in the amplifier. The
unity gain follower is the most sensitive configuration. In a
unity gain follower configuration, the KM4X70 amplifier
family requires a 510Ω series resistor to drive a 100pF load.
Power Dissipation
The maximum internal power dissipation allowed is directly
related to the maximum junction temperature. If the maximum
junction temperature exceeds 150°C, some performance
degradation will occur. If the maximum junction temperature
exceeds 175°C for an extended time, device failure may occur.

Layout Considerations
General layout and supply bypassing play major roles in high
frequency performance. Fairchild has evaluation boards to
use as a guide for high frequency layout and as aid in device
testing and characterization. Follow the steps below as a
basis for high frequency layout:
• Include 6.8µF and 0.01µF ceramic capacitors
• Place the 6.8µF capacitor within 0.75 inches of
the power pin
• Place the 0.01µF capacitor within 0.1 inches of
the power pin
• Remove the ground plane under and around the
part, especially near the input and output pins to
reduce parasitic capacitance
• Minimize all trace lengths to reduce series
inductances
Refer to the evaluation board layouts shown in Figure 6 for
more information.
When evaluating only one channel, complete the
following on the unused channel:
1. Ground the non-inverting input
2. Short the output to the inverting input

All dimensions are in millimeters (angle in degrees).
Dimensioning and tolerancing per ASME Y14.5–1994.
Dimensions "D" does not include mold flash, protusions or gate burrs. Mold flash protusions or gate burrs shall not exceed 0.15 per side .
Dimension "E1" does not include interlead flash or protusion. Interlead flash or protusion shall not exceed 0.25 per side.
Dimension "b" does not include dambar protusion. Allowable dambar protusion shall be 0.08mm total in excess of the "b" dimension at maximum
material condition. Dambar connot be located on the lower radius of the foot. Minimum space between protusion and adjacent lead is 0.07mm
for 0.5mm pitch packages.
