DESCRIPTION:
The MSK 3554 is a pin compatible, low gain stable, drop-in replacement for the OPA 3554 and TP 3554. The
MSK 3554 does not exhibit high frequency output oscillations like other versions of the 3554 when operated at
closed loop gains of less than 55 V/V. The extremely low input bias current and input offset voltage ratings coupled
with a high slew rate and wide bandwidth make the MSK 3554 an excellent choice for fast D/A converters, buffers,
pulse amplifiers and other high speed op-amp applications. The MSK 3554 is packaged in an 8-pin TO-3 using thick
film hybrid technology to obtain high reliability and compact size.

APPLICATION NOTES
HEAT SINKING
Refer to the following thermal model and governing equa-
tions to determine appropriate heat sinking for your application.
R
θSA
= ((T
J
- T
A
)/P
D
) - (R
θJC
) - (R
θCS
)
= ((125°C - 90°C) / .64W) - 37°C/W - .15°C/W
= 54.7 - 37.15
= 17.54°C/W
The heat sink in this example must have a thermal resistance
of no more than 17.54°C/W to maintain a junction temperature
of no more than +125°C.
Thermal Model:
OFFSET NULL
Typically, the MSK 3554(B) has an input offset voltage of
less than ±0.5mV. If it is desirable to adjust the offset closer
to "zero", or to a value other than "zero", the circuit below is
recommended. Rp should be a ten-turn 20KΩ potentiometer.
Typical offset adjust is ±20mV.

Example:
This example demonstrates a worst case analysis for the op-
amp output stage. This occurs when the output voltage is 1/2
the power supply voltage. Under this condition, maximum power
transfer occurs and the output is under maximum stress.
Conditions:

= ±8Vp Sine Wave, Freq. = 1KHZ

For a worst case analysis we will treat the +8Vp sine wave
as an 8 VDC output voltage.

COMPENSATION
The compensation capacitor is connected between pins 1
and 3 and is used to optimize bandwidth and slew rate while
maintaining circuit stability. The effect of compensation ca-
pacitance can be seen in the Bode Plot under the Typical Perfor-
mance Curves. As closed loop gain increases, compensation
capacitance can decrease and higher slew rates and wider band-
widths will be realized. See the component selection table for
recommended values of input and feedback resistance as well
as feedback capacitance and compensation capacitance.
