DESCRIPTION:
The MSK 0041 and 0041FP are general purpose Class C power operational amplifiers. These amplifiers offer high
output currents, making them an excellent low cost 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 0041 is available in a
hermetically sealed 12 pin TO-8 package. The MSK 0041FP is packaged in a 12 pin hermetic metal flatpack.

HEAT SINKING
CURRENT LIMIT
To select the correct heat sink for your application, refer to the
thermal model and governing equation below.
The MSK 0041 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 resistance
necessary to establish the desired current limit.
Thermal Model:

Governing Equation:
TJ = PD x (RθJC + RθCS + RθSA) + TA

Example: (TO-8 PACKAGE)
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 100 ohm load for 0.1 amp of
output current. For a worst case analysis we will treat the 0.1 amp
peak output current as a D.C. output current. The power supplies
are ±15 VDC.
POWER SUPPLY BYPASSING
1.) Find Power Dissipation
PD=[(quiescent current) X (+VCC - (VCC))] + [(VS - VO) X IOUT]
=(3.5 mA) X (30V) + (5V) X (0.1A)
=0.1W + 0.5W
=0.6W
2.) For conservative design, set TJ = +150°C.
3.) For this example, worst case TA = +25°C.
4.) RθJC = 85°C/W
5.) Rearrange governing equation to solve for RθSA:
RθSA = (TJ - TA) / PD - (RθJC) - (RθCS)
= (150°C - 25°C) / 0.6W - (85°C/W) - (0.15°C/W)
= 123°C/W
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 capacitor in parallel with a 4.7 microfarad tantalum
capacitor from each power supply pin to ground.This capacitor will eliminate any peak output voltage clipping which
may occur due to poor power supply load regulation. All
power supply decoupling capacitors should be placed as
close to the package power supply pins as possible.
SAFE OPERATING AREA
The heat sink in this example must have a thermal resistance of no
more than 123°C/W to maintain a junction temperature of less than
+150°C. This calculation assumes a case to sink thermal resistance
of 0.15°C/W.
3
The safe operating area curve is a graphical representation
of the power handling capability of the amplifier under various conditions. The wire bond current carrying capability,
transistor junction temperature and secondary breakdown
limitations are all incorporated into the safe operating area
curves. All applications should be checked against the curves
to ensure high M.T.B.F.
