A 3/03 APPLICATION NOTES 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 microfarad ceramic capacitor in parallel with a 4.7 microfarad tantalum capacitor from each power supply pin to ground. 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: 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) =(16V-8V) (8V/200Ω) =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) = (125°C - 100°C)/0.32W - 58°C/W - 0.15°C/W =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 junction 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 current that can be forced into the bases of the input transistors. Governing Equation: FEEDBACK RESISTORS TJ = PD X (RθJC + RθCS + RθSA) + TA 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 compensate and optimize the performance of the MSK0024.

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.
