DESCRIPTION:
The MSK 107RH 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 resistors.
These devices are also compensated with a single external capacitor. The MSK 107RH is packaged in a space
efficient, isolated 18 pin power package in three lead form configurations that can be directly attached to a heatsink.

APPLICATION NOTES
HEAT SINKING
CURRENT LIMIT
To select the correct heat sink for your application, refer to the
thermal model and governing equation below.
The MSK 107RH 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.
Thermal Model:
0.7V
RSC ~____
ISC
~
Current Limit Connection
Governing Equation:
TJ = PD X (RθJC + RθCS + RθSA) + TA
Where
TJ
PD
= Junction Temperature
= Total Power Dissipation
RθJC
RθCS
= Junction to Case Thermal Resistance
= Case to Heat Sink Thermal Resistance
RθSA = Heat Sink to Ambient Thermal Resistance
TC
TA
TS
= Case Temperature
= Ambient Temperature
= Sink Temperature
Example:
See "Application Circuits" in this data sheet for additional
information on current limit connections.
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.
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 10 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 107RH,
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.
1.) Find Power Dissipation
PD=[(quiescent current) X (+VCC - (VCC))] + [(VS - VO) X IOUT]
=(3.5 mA) X (30V) + (5V) X (1A)
=0.1W + 6W
=6.1W
2.) For conservative design, set TJ = +125°C.
3.) For this example, worst case TA = +25°C.
4.) RθJC = TBD°C/W
5.) Rearrange governing equation to solve for RθSA:
RθSA =(TJ - TA) / PD - (RθJC) - (RθCS)
= (125°C - 25°C) / 6.1W - (TBD°C/W) - (0.15°C/W)
= TBD°C/W
The heat sink in this example must have a thermal resistance of
no more than TBD°C/W to maintain a junction temperature of less
than +125°C.
