The gain can be setting by external input resistance. High PSRR and differential architecture provide increased immunity to noise and RF rectification. In addition to these features , a fast startup time and small package size make the APA2012 an ideal choice for both cellular handsets and PDAs. The APA2012 is capable of driving 1.3 W at 5 V or 600 m W at 3.6 V into 8 Ω. The APA2012 is also capable of driving 4 Ω. The APA2012 is designed with a Class-D architecture and operating with highly efficiency pared with Class-AB amplifier. It's suitable for power sensitive application, such as battery powered devices. The filterfree architecture eliminates the output filter, reduces the external ponent count, board area, and system costs, and simplifies the design. The APA2012 provides thermal and over circuit protection. Simplified Application Circuit INN Input Signal SHUTDOWN Bias...
