Product Summary

The TPA2012D2RTJR is a stereo, filter-free, Class-D audio amplifier (class-D amp) available in a WCSP, QFN, or PWP package. The TPA2012D2RTJR only requires two external components for operation. The TPA2012D2RTJR features independent shutdown controls for each channel. The gain can be selected to 6, 12, 18, or 24 dB utilizing the G0 and G1 gain select pins. 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 TPA2012D2RTJR class-D amp an ideal choice for both cellular handsets and PDAs. The applications of the TPA2012D2RTJR include Wireless or Cellular Handsets and PDAs, Portable DVD Player, Notebook PC, Portable Radio, Portable Gaming, Educational Toys, USB Speakers.
