Description

Power Management Products
The AP1158AEU and AP1151ADSXX are active filter IC for noise in the low frequency band in the various audio systems.
The AP1158AEU achieves miniaturization to 1.8 × 2.2 × 0.6 mm while maintaining low output noise performance of AP1158ADS. In addition, the AP1158AEU has significantly improved heat dissipation by adopting a package with a heat dissipation pad on the bottom surface, (Power Dissipation is 3 times higher than the AP1158ADS).
