KM4100/KM4101
Low Cost, +2.7V and +5V, 260MHz Rail-to-Rail Amplifiers
Features
General Description
The KM4100 (single) and KM4101 (single with
disable) are low cost, voltage feedback amplifiers.
These amplifiers are designed to operate on +2.7V,
+5V, or 2.5V supplies. The input voltage range
extends 300mV below the negative rail and 1.2V
below the positive rail.

Directly replaces AD8051 and LM7131 in single
supply applications
The KM4100 offers superior dynamic performance
with a 260MHz small signal bandwidth and 150V/µs
slew rate. The combination of low power, high
output current drive, and rail-to-rail performance
make the KM4100 well suited for battery-powered
communication/computing systems.

Small package options (SOT-23, SOIC)
The combination of low cost and high performance
make the KM4100 suitable for high volume applications
in both consumer and industrial applications such as
wireless phones, scanners, and color copiers.

General Description
f
The KM4100/KM4101 are single supply, general
purpose, voltage-feedback amplifiers fabricated on a
complementary bipolar process using a patent pending
topology. They feature a rail-to-rail output stage and
are unity gain stable. Both gain bandwidth and slew
rate are insensitive to temperature.

f
The common mode input range extends to 300mV
below ground and to 1.2V below V . Exceeding these
s
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 stay at the rail during this overdrive condition.

The design uses a Darlington output stage. The output
stage is short circuit protected and offers “soft”
saturation protection that improves recovery time.
f
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 reliability degradation will occur. If the maximum
junction temperature exceeds 175°C for an extended
time, device failure may occur.
The typical circuit schematic is shown in Figure 1.

The KM4100/KM4101 are short circuit protected.
However, this may not guarantee that the maximum
junction temperature (+150°C) is not exceeded under
all conditions. Follow the maximum power derating

response at a gain of +2, a feedback resistor of 1kΩ is
recommended. Figure 2 illustrates the KM4100/

Overdrive Recovery
Enable/Disable Function (KM4101)
The KM4101 offers an active-low disable pin that can
be used to lower its supply current. Leave the pin
floating to enable the part. Pull the disable pin to the
negative supply (which is ground in a single supply
application) to disable the output. During the disable
condition, the nominal supply current will drop to
below 127µA and the output will be at high impedance
with about 2pF capacitance.
For an amplifier, an overdrive condition 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 KM4100/KM4101 will typically recover
in less than 20ns from an overdrive condition. Figure
4 shows the KM4100 in an overdriven condition.

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 to 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
