In addition, the outside heat sink must be fastened onto a chassis for use. 2. Connect the cooling fin to GND potential. 3. Avoid short-circuit to V and short-circuit to GND, and load short-circuit. There is a danger of destruction under CC a special condition ...

... AN7199Z Technical Information (continued) [2] Application note (continued) 2. Oscillation countermeasures 1) In order to increase the oscillation allowance unnecessary to use a capacitor and a resistor between each output terminal and GND. How- ever, when inserting the capacitor for counter-measures against output line noise between the output terminal and GND, insert a resistor of approx ...
Page 13
... No shock noise is released. However, the changeover switch of the standby terminal may make a slight shock noise. In such a case, insert a capacitor of approx. 0.01 F between the standby terminal and GND. 2) Mute on/off No shock noise is released. Refer to the section on the mute function 350 Figure 5 AN7198Z, AN7199Z 1 3 AN7199Z V CC Constant Protection current source circuit 1.7 mA ...
Page 14
... When the attack time and recovery time are set less, pay attention to the IC with larger output offset because it may release the shock noise. 9. Voltage gain The voltage gain is fixed for the AN7198Z, and 40 dB for the AN7199Z not possible to change those values by the addition of an external resistor. 14 ...

... Precautions on misuse 1) Erroneous connection in the case of short-circuit to V The AN7198Z, AN7199Z have the breakdown voltage higher when an short-circuit to V short-circuit to GND or load short-circuit occur. However, there is a possibility of destruction, then smoke emission and ignition under a special condition. Avoid misuse and erroneous connection of the circuit. ...

... Application note (continued) 12. Precautions on misuse (continued) 3) Destruction mode for the AN7198Z, AN7199Z The AN7198Z, AN7199Z are the power ICs with high breakdown withstanding voltage but it has been found that the destruction occurs under special conditions. (1) GND-open short-circuit to GND Short-circuit of the output terminal to the GND terminal of power supply when GND terminal of the IC is open, or short-circuit to GND when the GND terminal of the IC is over 0 ...
