MIL-PRF-38534 CERTIFIED
DESCRIPTION:
The MSK 032 is a high speed, FET input, differential operational amplifier. Intended to replace the popular LH0032, the MSK 032 offers improved performance, much greater consistency from lot to lot, and improved stability over its operating temperature range. The MSK 032's wide bandwidth, accuracy and output drive capability make it a superior choice for applications such as video amplifiers, buffer amplifiers, comparator circuits and other high frequency signal transfer circuits. As with all MSK products, the MSK 032 is conservatively specified and is available in military and industrial grades.

APPLICATION NOTES HEAT SINKING
To determine if a heat sink is necessary for your application and if so, what type, refer to the thermal model and governing equation below.
Thermal Model:
RθSA= ((TJ - TA)/PD ) - (RθJC) - (RθCS). = ((125°C-100°C) /0.13W) - 187° C/W - 0.15°C/W = 192.3 - 187.15 = 5.2°C/W The heat sink in this example must have a thermal resistance of no more than 5.2°C/W to maintain a junction temperature of no more than+125°C.
SLEW RATE VS. SLEW RATE LIMIT
SLEW RATE
SR = 2πVpF: Slew rate is based upon the sinusoidal linear response of the amplifier and is calculated from the full power bandwidth frequency.
SLEW RATE LIMIT dv/dt: The slew rate limit is based upon the amplifier's response to a step input and is measured between 10% and 90%. MSK measures TR orTF, whichever is greater at±10VouT, RL=510Ω SRL= VO-20% TR or TF
COMPENSATION Governing Equation:
TJ=PD X (RθJC + RθCS + RθSA)+TA Where TJ= Junction Temperature PD= Total Power Dissipation RθJC=Junction to Case Thermal Resistance RθCS=Case to Heat Sink Thermal Resistance RθSA=Heat Sink to Ambient Thermal Resistance TC= Case Temperature TA= Ambient Temperature TS= Sink Temperature The MSK 032, can be frequency compens.
