The MSK 106RH is a Radiation Hardened Class C power operational amplifier. This amplifier offers large output
currents, making it an excellent choice for motor drive circuits. The amplifier and load can be protected from fault
conditions through the use of internal current limit circuitry that can be user programmed with two external resis-
tors. These devices are also compensated with a single external capacitor. The MSK 106RH is packaged in a 20
pin hermetic metal flatpack that is available with straight or gull wing leads.

HEAT SINKING
To select the correct heat sink for your application, refer to the
thermal model and governing equation below.

APPLICATION NOTES
CURRENT LIMIT
The MSK 106RH has an on-board current limit scheme
designed to limit the output drivers anytime output current
exceeds a predetermined limit. The following formula may
be used to determine the value of the current limit resis-
tance necessary to establish the desired current limit.

See "Application Circuits" in this data sheet for additional
information on current limit connections.
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 effec-
tive decoupling scheme consists of a 0.1 microfarad ceramic
capacitor in parallel with a 4.7 microfarad tantalum capacitor
from each power supply pin to ground. It is also a good
practice with high power op-amps, such as the MSK 106RH,
to place a 30-50 microfarad capacitor with a low effective
series resistance, in parallel with the other two power supply
decoupling capacitors. This capacitor will eliminate any peak
output voltage clipping which may occur due to poor power
supply load regulation. All power supply decoupling capaci-
tors should be placed as close to the package power supply
pins as possible.

Example:
In our example the amplifier application requires the output to
drive a 10 volt peak sine wave across a 10 ohm load for 1 amp of
output current. For a worst case analysis we will treat the 1 amp
peak output current as a D.C. output current. The power supplies
are 15 VDC.
1.) Find Power Dissipation

) X I
OUT
]
=(3.5 mA) X (30V) + (5V) X (1A)
=0.1W + 6W
=6.1W
2.) For conservative design, set T
J
= +125C.
3.) For this example, worst case T
A
= +25C.
4.) R
JC
= 6.0C/W
5.) Rearrange governing equation to solve for R
SA:
R
SA
=(T
J
- T

) / P
D
- (R
JC
) - (R
CS
)
= (125C - 25C) / 6.1W - (6.0C/W) - (0.15C/W)
= 10.2C/W
The heat sink in this example must have a thermal resistance of
no more than 10.2C/W to maintain a junction temperature of less
than +125C.
