AN7190NK
1.2+0.1
The AN7190NK and the AN7190NZ are audio power
ICs developed for the sound output of car audio (dual 20
W). It is incorporating various protective circuits to protect the IC from destruction by GND-open, short circuit
to GND and power supply surge which are the important
subject of power IC protection, so the IC will largely
contribute to a high reliability design of equipment. Also,
it is incorporating a perfect muting circuit which is free
from shock noise, so that a shock noise design under the
set transient condition can be made easily using together
with its standby function.

■ Usage Notes
1. Always attach an outside heat sink when using the chip. Note that, 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 VCC and short circuit to GND, and load short-circuit.
4. The temperature protection circuit will be actuated at Tj = approx. 150°C, but it is automatically reset when the chip
temperature drops below the above set level.
5. The overvoltage protection circuit starts its operation at VCC = approx. 20 V.
6. Take into consideration the heat radiation design particularly when VCC is set high or when the load is 2 Ω.
7. When the beep sound function is not used, open the beep sound input pin (pin 10) or connect it to pin 9 with around
0.01 µF capacitor.
8. Connect only pin 9 (ground, signal source) to the signal GND of the amplifier in the previous stage. The characteristics such as distortion, etc. will improve.
