General Description:
The AN7500FHQ is a single chip IC optimum for a 1.5 V headphone stereo system including pre-amp., power amp. and Dolby B type noise reduction circuit. Current consumption in a Dolby circuit off mode has been drastically reduced and an operating supply voltage has also been lowered to 0.98 V. Much fewer external components have been realized due to an integration of audio signal processing system into a single chip circuitry in a small outline package and space saving mounting of a set.

General Description:
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.
