Overview
ICs for Audio Common Use AN7190NK, AN7190NZ Dual 20 W BTL power amplifier s 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 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.

05 s Features • BTL 20 W × 2-channel (4 Ω), 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 capacitors.
Muting function is not required, and power supply choke coil is unnecessary.
• Provided with beep sound input pin • 2 Ω load guaranteed HZIP016-P-0665A AN7190NZ 18.
