DESCRIPTION:
The MSK 0024 is a wide bandwidth, high slew rate operational amplifier ideally suited for use as a buffer to A to
D and D to A converters and high speed comparators. The device is internally compensated and will remain stable
when driving a capacitive load. The MSK 0024 is also a pin similar replacement for the popular LH0024. The MSK
0024 is internally compensated and can replace the LH0024 in most applications without any changes to existing
circuitry. The device is packaged in a hermetically sealed 8 pin metal can.

HEAT SINKING
To determine if a heat sink is necessary for your appli-
cation and if so, what type, refer to the thermal model
and governing equation below.
Thermal Model:
Governing Equation:
T
J
=
P
D
X (R
JC
+ R
CS
+ R
SA
) + T
A
Where
T
J
= Junction Temperature
P
D
= Total Power Dissipation
R
JC
= Junction to Case Thermal Resistance
R
CS
= Case to Heat Sink Thermal Resistance
R
SA
= Heat Sink to Ambient Thermal Resistance
T
C
= Case Temperature
T
A
= Ambient Temperature
T
S
= Sink Temperature
Example:
The 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 con-
dition, maximum power transfer occurs and the output
is under maximum stress.
Conditions:
V
CC
=16VDC
V
OUT
=8Vp Sine Wave, Freq.=1KHz
R
L
=200
For a worst case analysis we treat the +8Vp sine wave
as an 8 VDC output voltage.

)
=(16V-8V) (8V/200
)
=320mW
2.) For conservative design, set T
J
=+125C.
3.) For this example, worst case T
A
=+100C.
4.) R
JC
= 58C/W from MSK 032B Data Sheet.
5.) R
CS
=0.15C/W for most thermal greases.
6.) Rearrange governing equation to solve for R
SA
:
R
SA
= ((T
J
-
T
A
) / P
D)
- (R
JC
) - (R
CS
)
= (125C - 100C)/0.32W - 58C/W - 0.15C/W
=78.1 - 58.15
=19.9C/W
The heat sink in this example must have a thermal
resistance of no more than 19.9C/W to maintain a junc-
tion temperature of less than +125C.
INPUT CONSIDERATIONS
An input resistor (RIN below) is required in circuits
where the input to the MSK0024 will be subjected to
transient or continuous voltages exceeding the 6V
maximum differential limit. This resistor will limit the cur-
rent that can be forced into the bases of the input tran-
sistors.
FEEDBACK RESISTORS
Feedback resistors should be of low enough value
(<5K recommended) to ensure that the time constant
formed with the capacitance at the summing junction
will not limit amplifier performance. If a larger resistor
must be used, a small (< 10pF) feedback capacitor may
be used in parallel with the feedback resistor to compen-
sate and optimize the performance of the MSK0024.
TYPICAL APPLICATION CIRCUIT
POWER SUPPLY BYPASSING
Both the negative and 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 micro-
farad ceramic capacitor in parallel with a 4.7 microfarad
tantalum capacitor from each power supply pin to ground.
