    • Any and all SANYO products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft’s control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage. Consult with your SANYO representative nearest you before using any SANYO products described or contained herein in such applications. SANYO assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges,or other parameters) listed in products specifications of any and all SANYO products described or contained herein.

All tests are made using a constant-voltage supply unless otherwise specified. Available time for load short-circuit and output noise voltage are measured using the transformer supply specified below. The output noise voltage is the peak value of an average-reading meter with an rms value scale (VTVM). A regulated AC supply (50Hz) should be used to eliminate the effects of AC primary line flicker noise.

    • Specifications of any and all SANYO products described or contained herein stipulate the performance, characteristics, and functions of the described products in the independent state, and are not guarantees of the performance, characteristics, and functions of the described products as mounted in the customer's products or equipment. To verify symptoms and states that cannot be evaluated in an independent device, the customer should always evaluate and test devices mounted in the customer's products or equipment. SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all semiconductor products fail with some probability. It is possible that these probabilistic failures could give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire, or that could cause damage to other property. When designing equipment, adopt safety measures so that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective circuits and error prevention circuits for safe design, redundant design, and structural design.

STK41322 PS No.2668–8/8 When estimating the power dissipation for an actual audio signal input, the rule of thumb is to select Pd correspond- ing to (1/10) × PO max (within safe limits) for a continuous sine wave input. For example, Pd=18.6W for 8Ω, and Pd=23W for 4Ω The heatsink thermal resistance, θj-a, required to dissipate the STK41322 device total power dissipation, Pd, is deter- mined as follows : Condition 1: IC substrate temperature not to exceed 125°C TC=Pd×θc-a+Ta<125°C ..................................... (1) where Ta is the guaranteed maximum ambient temperature. Condition 2: Power transistor junction temperature, Tj, not to exceed 150°C Tj=Pd×θc-a+Pd/4×θj-c+Ta<150°C .................... (2) The STK41322 has 4 power transistors (2 per channel), and the thermal resistance per transistor, θj-c, is 3.0°C/W. Therefore, equation 2 becomes : Pd× (θc-a+3.0/4)+Ta<150°C .............................. (3) The required heatsink must have a thermal resistance that satisfies both expressions 1 and 3. Figure 3 shows the am- bient temperature parameter against Pd and θj-a calculated from equations 1 and 3. Figure 3. θc-a – Pd For example, a stereo amplifier with ambient temperature of Ta=50°C needs a heatsink with thermal resistance given by the following : For VCC=±23V, RL=8Ω : 1/10 PO max corresponds Pd1=18.6W From figure 3, the STK41322 thermal resistance is θc-a1=4.01°C/W From equation 3, this results in a junction temperature Tj=139.1°C For VCC=±20V, RL=4Ω : 1/10 PO max corresponds Pd2=23W From figure 3, the STK41322 thermal resistance is θc-a2=3.26°C/W From equation 3, this results in a junction temperature Tj=142.3°C
