SDE00029BEB Stereo BTL amplifier IC with built-in AGC (I2C bus-control correspondence) - Overview AN12975A is the stereo BTL amplifier which contained the AGC circuit for clip prevention of a speaker output. This IC performs a mode change by the I2C bus control system.(Standby function ON/OFF change etc.) - Features y Selection by I2C bus control is possible in the on-level of AGC. (3-bit, 8-step) y Selection by I2C bus control is possible in an attack/recovery time of AGC. (attack: 2-bit , recovery: 3-bit) y The resistance and the capacitor of a detector circuit which were being used for the conventional AGC are unnecessary. y In order to realize high efficiency of output power, it adopts CMOS power amplifier circuit . - Applications y Audio amplifier for mobile, such as a cellular phone - Package y 20 pin plastic non lead package of four directions (LGA Type) - Type y Silicon Monolithic Bi-CMOS IC ..
