KM4100/KM4101
Low Cost, +2.7V and +5V, 260MHz Rail-to-Rail Amplifiers
General Description
Features
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.

■
Fully specified at +2.7V
and +5V supplies

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.

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

The common mode input range extends to 300mV below
ground and to 1.2V below V . Exceeding these values
s
will not cause phase reversal. However, if the input volt-
age 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.

Overdrive Recovery
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 ground (ie.
negative supply) 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 over-
driven 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. KOTA 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
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
