4707 Dey Road Liverpool, N.Y. 13088 (315) 701-6751 MIL-PRF-38534 QUALIFIED 0024 ISO-9001 CERTIFIED BY DSCC M.S.KENNEDY CORP. FEATURES: High Speed DAC Buffer High Speed Flash ADC Buffer High Speed Cable Driver Imaging Equipment HIGH SPEED OPERATIONAL AMPLIFIER EQUIVALENT SCHEMATIC TYPICAL APPLICATIONS DESCRIPTION: The MSK 0024 is a wide bandwidth, high slew rate operational amplifier ideally suited for use as a buffer to A to D and D to A converters and high speed comparators. The device is internally compensated and will remain stable when driving a capacitive load. The MSK 0024 is also a pin similar replacement for the popular LH0024. The MSK 0024 is internally compensated and can replace the LH0024 in most applications without any changes to existing circuitry. The device is packaged in a hermetically sealed 8 pin metal can.

Rev. A 3/03 HEAT SINKING To determine if a heat sink is necessary for your appli- cation and if so, what type, refer to the thermal model and governing equation below. Thermal Model: 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 Example: The example demonstrates a worst case analysis for the op-amp output stage. This occurs when the output voltage is 1/2 the power supply voltage. Under this con- dition, maximum power transfer occurs and the output is under maximum stress. Conditions: VCC=±16VDC VOUT=±8Vp Sine Wave, Freq.=1KHz RL=200Ω For a worst case analysis we treat the +8Vp sine wave as an 8 VDC output voltage. 1.) Find driver power dissipation PD=(VCC-VOUT) (VOUT/RL) =320mW 2.) For conservative design, set TJ =+125°C. 3.) For this example, worst case TA =+100°C. 4.) RθJC = 58°C/W from MSK 032B Data Sheet. 5.) RθCS=0.15°C/W for most thermal greases. 6.) Rearrange governing equation to solve for RθSA: RθSA= ((TJ - TA) / PD) - (RθJC) - (RθCS) =78.1 - 58.15 =19.9°C/W The heat sink in this example must have a thermal resistance of no more than 19.9°C/W to maintain a junc- tion temperature of less than +125°C. INPUT CONSIDERATIONS An input resistor (RIN below) is required in circuits where the input to the MSK0024 will be subjected to transient or continuous voltages exceeding the ±6V maximum differential limit. This resistor will limit the cur- rent that can be forced into the bases of the input tran- sistors. FEEDBACK RESISTORS Feedback resistors should be of low enough value (<5K recommended) to ensure that the time constant formed with the capacitance at the summing junction will not limit amplifier performance. If a larger resistor must be used, a small (< 10pF) feedback capacitor may be used in parallel with the feedback resistor to compen- sate and optimize the performance of the MSK0024. TYPICAL APPLICATION CIRCUIT POWER SUPPLY BYPASSING Both the negative and 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 micro- farad ceramic capacitor in parallel with a 4.7 microfarad tantalum capacitor from each power supply pin to ground.
