AN7190NK, AN7190NZ Dual 20 W BTL power amplifier n Overview 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 pro- tect 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. n Features

• BTL 20 W · 2-channel (4 W ), GV = 40 dB
• Built-in various protection circuits (thermal protection, short circuit to VCC and short circuit to GND, VCC -open short circuit to VCC , GND-open short circuit to GND, overvoltage and supply surge, and ASO, etc.) Especially, the supply surge breakdown voltage is 100 V or more. GND open breakdown voltage is 16 V or more.
• Built-in standby function Free from shock noise at STB on/off.
• Built-in muting function Free from shock noise at mute-on/off. Adapting attenuator method so that abnormal sound due to waveform deformation is not generated . Attack time, recovery time are 50 ms or less.
• Reduction in external components It eliminates the need for NF and BS electrolytic ca- pacitors. Muting function is not required, and power supply choke coil is unnecessary.

AN7190NK, AN7190NZ ICs for Audio Common Use n 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 V CC 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 W . 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 mF capacitor. 8. Connect only pin 9 (ground, signal source) to the signal GND of the amplifier in the previous stage. The character- istics such as distortion, etc. will improve. 100 120 113.6 40.3 59.5 30.5 20.5 11.3 1.8 0 25 50 75 100 125 150 Ambient temperature Ta (°C) Power dissipation PD (W) Infinite heat sink 1°C/W heat sink 2°C/W heat sink 3°C/W heat sink 5°C/W heat sink 10°C/W heat sink Without heat sink R th (j-c) = 1.1°C/W R th (j-a) = 68.3°C/W n Technical Information
