ICs for Audio Common Use AN7191NZ Dual 20 W BTL audio power amplifier s Overview The AN7191NZ is an audio power IC 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. 18.00±0.30 13.50±0.30 1.50±0.10 Unit : mm 4.00±0.20 φ3.60±0.10 1 1.27 0.50+0.20 –0.10 15 (0.61) (1.80) (2.54) 2.40±0.50 R0.55 (1.95) 0.25+0.
