DESCRIPTION:
MSK0021FPG
The MSK 0021, 0021FP and 0021FPG are general purpose Class C power operational amplifiers. These amplifiers
offer large 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 0021 is available
in a hermetically sealed 8 pin TO-3 package. The MSK 0021FP is packaged in a 20 pin hermetic metal flatpack and the
0021FPG is lead formed by MSK.

HEAT SINKING
CURRENT LIMIT
To select the correct heat sink for your application, refer to the
thermal model and governing equation below.
The MSK 0021 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

POWER SUPPLY BYPASSING
Example: (TO-3 PACKAGE)
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
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 = +150°C.
3.) For this example, worst case TA = +25°C.
4.) RθJC = 2.0°C/W typically for the TO-3 package.
5.) Rearrange governing equation to solve for RθSA:
RθSA = (TJ - TA) / PD - (RθJC) - (RθCS)
= (150°C - 25°C) / 6.1W - (2.0°C/W) - (0.15°C/W)
= 18.5°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. It is also a
good practice with high power op-amps, such as the MSK
0021, 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 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 18.5°C/W to maintain a junction temperature of less than
+150°C.
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 S.O.A.
curves to ensure high M.T.B.F.
