heat sinking to select the correct heat sink for your application, refer to the thermal model and governing equation below. thermal model: application notes current limit the msk 106rh has an on-board current limit scheme de- signed to limit the output drivers anytime output current ex- ceeds a predetermined limit. the following formula may be used to determine the value of the current limit resistance nec- essary to establish the desired current limit. current limit connection 3 r sc = 0.7 i sc ___ see "application circuits" in this data sheet for additional infor- mation on current limit connections. power supply bypassing 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 ca- pacitor 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 106rh, to place a 30-50 microfarad capacitor with a low effective series resis- tance, in parallel with the other two power supply decoupling capacitors. this capacitor will eliminate any peak output volt- age 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. governing equation: t j = p d x (r q jc + r q cs + r q sa ) + t a where t j = junction temperature p d = total power dissipation r q jc = junction to case thermal resistance r q cs = case to heat sink thermal resistance r q sa = heat sink to ambient thermal resistance t c = case temperature t a = ambient temperature t s = sink temperature example: 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 p d =[(quiescent current) x (+v cc - (v cc ))] + [(v s - v o ) x i out ] =(3.5 ma) x (30v) + (5v) x (1a) =0.1w + 6w =6.1w 2.) for conservative design, set t j = +125c. 3.) for this example, worst case t a = +25c. 4.) r q jc = 6.0c/w 5.) rearrange governing equation to solve for r q sa: r q sa =(t j - t a ) / p d - (r q jc ) - (r q cs ) = (125c - 25c) / 6.1w - (6.0c/w) - (0.15c/w) = 10.2c/w the heat sink in this example must have a thermal resis- tance of no more than 10.2c/w to maintain a junction tem- perature of less than +125c. rev. f 6/08 radiation performance curves for tid testing have been generated for all radiation testing performed by ms kennedy. these curves show performance trends throughout the tid test process and can be located in the msk 106rh radiation test report. the complete ra- diation test report is available in the rad hard prod- ucts section on the msk website. total dose radiation test performance http://www.mskennedy.com/store.asp?pid=9951&catid=19680
