1 / 23 page TPA2010D1 SLOS417A − OCTOBER 2003 − REVISED DECEMBER 2003 2.5W MONO FILTERFREE CLASSD AUDIO POWER AMPLIFIER FEATURES D Maximum Battery Life and Minimum Heat − Efficiency With an 8- Ω Speaker: − 88% at 400 mW − 80% at 100 mW − 2.8-mA Quiescent Current − 0.5- µA Shutdown Current D Only Three External Components − Optimized PWM Output Stage Eliminates LC Output Filter − Internally Generated 250-kHz Switching Frequency Eliminates Capacitor and Resistor − Improved PSRR (−75 dB) and Wide Supply Voltage (2.5 V to 5.5 V) Eliminates Need for a Voltage Regulator − Fully Differential Design Reduces RF Rectification and Eliminates Bypass Capacitor − Improved CMRR Eliminates Two Input Coupling Capacitors D Wafer Chip Scale Packaging (WCSP) − NanoFree E Lead-Free (YZF) − NanoStar E SnPb (YEF) APPLICATIONS D Ideal for Wireless or Cellular Handsets and PDAs DESCRIPTION The TPA2010D1 is a 2.5-W high efficiency filter-free class-D audio power amplifier in a 1.45 mm × 1.45 mm wafer chip scale package (WCSP) that requires only three external components. Features like 88% efficiency, −75-dB PSRR, improved RF-rectification immunity, and 8 mm2 total PCB area make the TPA2010D1 ideal for cellular handsets. A fast start-up time of 1 ms with minimal pop makes the TP2010D1 ideal for PDA applications. In cellular handsets, the earpiece, speaker phone, and melody ringer can each be driven by the TPA2010D1. The TPA2010D1 allows independent gain while summing signals from seperate sources, and has a low 36 µV noise floor, A-weighted.
