AN7555Z
BTL output power IC for car audio
s Overview
Unit : mm
The AN7555Z is an audio power IC developed as the sound output of car audio (35 W × 4-channel). It has realized the voltage gain of 40 dB based on the AN7550NZ

that a space saving of set is possible. Also, it incorpo-
rates 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.
