DESCRIPTION:
The MSK 0032 is a high speed, FET input, differential amplifier designed to replace the popular LH0032 and
TP0032. Since the MSK 0032 requires less compensation than the LH0032, it exhibits wider bandwidth and greater
stability. The MSK 0032 can be used as a direct replacement in current designs using the LH0032 or TP0032 with no
changes to compensation schemes. High frequency signal transfer circuits such as video amplifiers, high speed
integrators and comparators are just a few of the applications that the MSK 0032 is well suited for.

APPLICATION NOTES
HEAT SINKING
Since the case of the MSK 0032 only runs approximately
40°C hotter than the ambient temperature, a heat sink is gen-
erally not necessary. However, in applications where it is criti-
cal to minimize input bias current, a heat sink may be used.The
case of the MSK 0032 is isolated from the internal circuitry so
the heat sink may be attached directly to the case. The heat
sink may however create enough parasitic capacitance at the
pins to necessitate adjusting the amount of compensation used.
COMPENSATION
When replacing an LH0032 or TP0032 with an MSK 0032,
no changes in compensation need be made. The MSK 0032
will demonstrate greater loop stability than the LH0032 and
loop stability very similar to the TP0032. As with any opera-
tional amplifier, a feedback capacitor in the range of 2-10pF is
recommended to compensate for the effect of the R-C time
constant created by the input capacitance of the op-amp and
the feedback and input resistors in an inverting configuration.
See Figure 3 and Figure 4 for recommended compensation
schemes for non-inverting configurations.
INPUT OFFSET VOLTAGE NULL
Figure 3
Figure 1
The input offset voltage of the MSK 0032 is typically less
than ±0.5mV. If it is necessary to null the offset to zero or
some value other than zero, the above circuit is recommended.
Typical offset adjust range is 25mV.
Figure 4
POWER SUPPLY BYPASSING
Both the negative and the positive power supplies must be
effectively decoupled with a high and low frequency bypass
circuit to avoid power supply induced oscillation. An effective
decoupling scheme consists of a 0.1 microfarad ceramic ca-
pacitor in parallel with a 4.7 microfarad tantalum capacitor from
each power supply pin to ground.
