IS31AP2117

IS31AP2117 8W/CH STEREO CLASS-D AUDIO POWER AMPLIFIER Advanced Information July 2012 GENERAL DESCRIPTION The IS31AP2117 is an 8W/CH, dual channel, Class-D stereo driver in our audio amplifier family. It is suitable for powering the audio components of various equipments, including typical consumer electronics, high performance audio speakers. IS31AP2117 has several key features which distinguishes itself from other alternatives on the market. On-board AGC, EMI suppression, and 92% typical operating efficiency are key features of this part. EMI suppression circuit, which eliminates LC, filters at the outputs. These features simplify customer design, reduces system cost and PCB area. The IS31AP2117 integrates automatic gain control function with adjustable power limit. When output power goes over the power limit, IS31AP2117 can reduce gain automatically to pull down the output power, so that keep the output power around power limit while the input level is high. The IS31AP2117 has short circuit and thermal protection features integrated on board.
