ISO 9001 CERTIFIED BY DSCC M.S.KENNEDY CORP. 4707 Dey Road Liverpool, N.Y. 13088 HIGH SPEED, BUFFER AMPLIFIER AMP 0002 MIL-PRF-38534 CERTIFIED (315) 701-6751 FEATURES: Industry Wide LH0002 Replacement High Input Impedance-180K Min Low Output Impedance-10 Max Low Harmonic Distortion DC to 30 MHz Bandwidth Slew Rate is Typically 400 V/?S Operating Range from?5V to ?20V Available to DSCC SMD5962-7801301XC DESCRIPTION: The MSK 0002 is a general purpose current amplifier. It is the industry wide replacement for the LH0002. The device is ideal for use with an operational amplifier in a closed loop configuration to increase current output. The MSK 0002 is designed with a symmetrical output stage that provides low output impedances to both the positive and negative portions of output pulses. The MSK 0002 is packaged in a hermetic 8 lead low profile T0-5 header and is specified over the full military temperature range.

RSA = ((TJ - TA)/PD) - (RJC) - (RCS) = ((125?C - 80?C) / 0.36W) - 40?C/W - 0.15?C/W = 125 - 40.15 = 84.9?C/W This heat sink in this example must have a thermal resistance of no more than 84.9?C/W to maintain a junction temperature of no more than +125?C. Thermal Model: Typical Applications: Governing Equation: TJ=PD X (RJC +RCS +RSA) +TA Where TJ=Junction Temperature PD=Total Power Dissipation RJC=Junction to Case Thermal Resistance RCS=Heat Sink to Ambient Thermal Resistance TC=Case Temperature TA=Ambient Temperature TS=Sink Temperature Example: This example demonstrates a worst case analysis for the buffer output stage. This occurs when the output voltage is 1/2 the power supply voltage. Under this condition, maximum power transfer occurs and the output is under maximum stress. Conditions: VCC= ?12VDC Vo= ?6Vp Sine Wave, Freq. = 1KHz RL= 100 For a worst case analysis we will treat the ?6Vp sine wave as an 6 VDC output voltage. 1.) Find Driver Power Dissipation PD= (Vcc-Vo) (Vo/RL) = (12V-6V) (6V/100) = 360mW 2.) For conservative design, set TJ=+125?C Max. 3.) For this example, worst case TA=+80?C 4.) RJC = 40? C/W from MSK 0002H Data Sheet 5.) RCS = 0.15? C/W for most thermal greases 6.) Rearrange governing equation to solve for RSA 3 Rev. - 10/00 TYPICAL PERFORMANCE CURVES 4 Rev. - 10/00 MECHANICAL SPECIFICATIONS ALL DIMENSIONS ARE ?0.010 INCHES UNLESS OTHERWISE LABELED ORDERING INFORMATION Part Number MSK0002 MSK0002H 7801-301XC Screening Level Industrial Military-Mil-PRF-38534 DSCC-SMD 4707 Dey Road, Liverpool, New York 13088 Phone (315) 701-6751 FAX (315) 701-6752 www.mskennedy.com The information contained herein is believed to be accurate at the time of printing.
