GENERAL DESCRIPTION
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 also capable of driving 4 Ω. The APA2012 is designed with a Class-D architecture and operating with highly efficiency compared with Class-AB amplifier.
