Definition of terms

FIG1. Simplified Illustration of IC PD: Power Dissipation and Heat Sink attached Tj: Junction Temperature TC: Case Temperature TA: Ambient Temperature JC: Thermal Resistance of junction to case CA: Thermal Resistance of case to ambient, normally through heat sink
The following two equations represent the relations of these terms. ( Tj - TC ) / JC = PD (1) ( TC - TA ) / CA = PD' (2) For reliable and long-term, continuous operation, junction temperature should not exceed 125OC and JC for FP-12S package is 2OC/W. Substitute these values in Equation 1. After specify the PD, TC can be determined. Assume no heat loss at the casing,i.e. all power is dissipated to the ambient through heat sink, which is quite true. So PD = PD'. Since TC is also known, one can determine the following using equation2: a) The rating of heat sink for specific maximum operating ambient temperature, or b) The maximum operating ambient temperature for specific heat sink rating. A more general equation can be used for rough calculation. ( TJ - TA ) / JA = PD JA = CA + JC (3) (4)
In this case, JA is total thermal resistance of the heat sink and IC package. Therefore, for specified power dissipation, either heat sink rating or maximum operating ambient temperature can be decided if the other is known. Take note that it's essential to know PD value before hand in order to work out other quantities. PD calculation is as shown. PD = Vcc x Icc - Po_total Vcc: DC supply voltage Icc: RMS value of IC current Po_total: Total output power

Input DC biasing
5 20k
Vin
Input DC bias is maintained at ground level. If the input signal contains DC bias voltage, AC coupling should be included on the application circuit. The value of 20k resistor is set in order to achieve the minimum output DC offset.
FIG2. Input DC Biasing
Output Zobel Network
It should be noted that this device is designed such that the Zobel network (RC pair) at the output pins is not necessary for stable operation. In practical application, the Zobel network may be applied optionally for two reasons: a) Ensuring stability for different PCB layout and speaker types. b) Ability to withstand to high ESD levels.

Standby operation
51k

STB
10F
Standby pin should be connected with carefully selected components in order to avoid "Pop Noise" during Standby ON/OFF transient. The 51k resistor and 10uF capacitor pair can delay the rising of voltage at pin 5 to reach the Standby threshold. When Standby is switching on together with supply, this delay would be very useful to ensure no "Pop Noise".
FIG4. Standby Application circuit
If the Standby voltage is provided by a microcontroller, the suppression of "Pop" could even be better. For further details of timing and delay for standby circuit, please refer to page 11.
Mute operation
Mute pin should be connected with carefully selected components in order to avoid "Pop Noise" during MUTE ON/OFF transient. The 8.2k resistor and 33uF capacitor pair can delay the rising of voltage at pin 6 to reach the Mute threshold. When Mute is switching on together with supply, this delay would be very useful to ensure no "Pop Noise". 8.2k

(Precaution for use)
1) Ground the radiation fin so that there will be no difference in electric potential between the radiation fin and ground. 2) The thermal protection circuit operates at Tj at approximately 150 C. Thermal protection circuit is reset automatically when the temperature drops. 3) Be sure to attach heatsink to the IC before use. Make sure that the heatsink is secured to the chassis. 4) In order to prevent IC from being damaged during the fault test, prior to standby switching from on to off or vice versa, it is important to assert the mute on. Please refer to the timing diagram on page 11.
