AN7560

ICs for Audio Common Use AN7560Z BTL output power IC for car audio s Overview The AN7560Z is an audio power IC developed as the sound output of car audio (35 W by 4-ch.). A capacitor and resisitor to stop oscillation are built in between the output pin and GND so that a space saving of set is possible. Also, it incorporates a perfect muting circuit without shock noise so that a shock noise design under the set transient condition can be made easily when used together with its standby function. In addition, it incorporates various protection circuits to protect the IC from destruction by GND-open-shortcircuit to ground and power supply surge which are the important subject of power IC protection. This IC will largely contribute to a high reliability design of the equipment. 31.0±0.3 27.0±0.3 21.0±0.1 (10.50) (10.50) 3.6±0.1 Unit: mm 4.5±0.2 φ3.6±0.1 1.5±0.1 3.75±0.10 14.5±0.3 15.5±0.3 (1.26) 1.27 0.6 +0.2 –0.1 (5.08) (4.29) 0.40 +0.15 –0.05 (2.15) Seating plane s Features • A pattern layout in which input and output pattern do not intersect each other on single-sided printed circuit board is possible. • Incorporating various protection circuits (temperature, shortcircuit to VCC, VCC-open short circuit to VCC, shortcircuit to GND, GND-open short circuit to GND, overvoltage, power supply surge, and ASO, etc.) • Built-in standby function (shock noise-free when STBon/off) • Built-in muting function (shock noise-free when Muteon/off) • External components reduction • Provided with beep sound input pin • Equipped with auxiliary sound input pin HZIP025-P-0980 s Applcations • Car stereo, miniature audio component, karaoke and other audio equipment.
