General Description
The KM4200 is a single supply, general purpose, voltage-
feedback amplifier fabricated on a complementary
bipolar process using a patent pending topography. It
features a rail-to-rail output stage and is 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
s
. 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 stay at the rail during this overdrive condition.
The design uses a Darlington output stage. The out-
put stage is short circuit protected and offers
“
soft
”
saturation protection that improves recovery time.
The typical circuit schematic is shown in Figure 1.
Figure 1: Typical Configuration
At non-inverting gains other than G = +1, keep R
g
below 1k
to minimize peaking; thus, for optimum
response at a gain of +2, a feedback resistor of 1k
is
recommended. Figure 2 illustrates the KM4200
frequency response with both 1k
and 2k
feedback
resistors.

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 KM4200 is short circuit protected. However, this
may not guarantee that the maximum junction tem-
perature (+150
°
C) is not exceeded under all conditions.
Follow the maximum power derating curves shown in
Figure 3 to ensure proper operation.

Overdrive Recovery
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 KM4200 will typically recover in less
than 20ns from an overdrive condition. Figure 4
shows the KM4200 in an overdriven condition.
