Ordering number : EN4339A Thick Film Hybrid IC STK400-040 AF Power Amplifier (Split Power Supply) (25 W + 25 W + 25 W min, THD = 0.4%) Overview Now, thick-film audio power amplifier ICs are available with pin-compatibility to permit a single PCB to be designed and amplifier output capacity changed simply by installing a hybrid IC. This new series was developed with this kind of pin-compatibility to ensure integration between systems everywhere. With this new series of IC, even changes from 3-channel amplifier to 2-channel amplifiers is possible using the same PCB. In addition, this new series of ICs has a 6/3 Ω drive in order to support the low impedance of modern speakers.

When capacitor reactance with low frequency is increased, the reactance value should be reduced in order to reduce the output noise from the signal resistance dependent 1/f noise. In response to the popping noise which occurs when the system power is turned on, C1 and C11 which determine the decay time constant on the input side are increased while C3, C13 and C23 on the NF side are decreased. For input filter capacitor. Permits high-region noise reduction by utilizing filter constructed with R1, R11 and R21. For NF capacitor. This capacitor determines the decline of the cut-off frequency and is calculated according to the following equation. fL = 1 2π X C3 (13, 23,) X R3 (13, 23) C2, 12, 22 C3, 13, 23 For the purpose of achieving voltage gains prior to reduction, it is best that C3, C13 and C23 are large. However, because the shock noise which occurs when the system power is turned on tends to increase, values larger than those absolutely necessary should be avoided. C5, 15, 25 C6, 7 For oscillation prevention capacitor. A Mylar capacitor with temperature and frequency features is recommended. For oscillation prevention capacitor. To ensure safe IC functioning, the capacitor should be installed as close as possible to the IC power pin to reduce power impedance. An electrolytic capacitor is good. For decoupling capacitor. Reduces shock noise during power up using decay time constant circuits with R8, R9, R28 and R29 and eliminates components such as ripples crossing over into the input side from the power line. For input filter applied resistor. For input bias resistor. The input pin is biased to zero potential. Input impedance is mostly decided with this resistance value. For resistors to determine voltage gain (VG). We recommend a VG = 40 dB using R3, R13, R23 = 560Ω and R4, R14 and R24 = 56Ω. VG adjustments are best performed using R3, R13 and R23. When using R4, R14 and R24 for such purposes, R4, R14 and R24 should be set to equal R2, R12 and R22 in order to establish a stable VN balance. For oscillation prevention resistor. For oscillation prevention resistor. This resistor’s electrical output resides in the signal frequency and is calculated according to the following formula. VCC max/√2 2 P R6 (16, 26) = ( 1/2π fC5 (15, 25) + R6 (16, 26) ) X R6 (16, 26) f = output signal frequency upper limit R8, 9, 28, 29 For ripple filter applied resistor. PO max, ripple rejection and power-up shock noise are modified according to this value. Set the electrical output of these resistors while keeping in mind the flow of peak current during recharging to C8, C9, C28 and C29 which function as pre-drive TR control resistors during load shorts. For oscillation prevention coil. Compensates phase dislocation caused by load capacitors C8, 9, 28, 29 R1, 11, 21 R2, 12, 22 R3, 13, 23 R4, 14, 24 R5, 15, 25 R6, 16, 26 L1, 2, 3 and ensures stable oscillation.
