SLOS546 – MAY 2008 2.5-W MONO FILTER-FREE CLASS-D AUDIO POWER AMPLIFIER • Ideal for Wireless or Cellular Handsets and 2 • Pin-to-Pin Compatibility with TPA2010D1 PDAs • 32 ms Start-up Time Eliminates CODEC Click/Pop noise • Maximum Battery Life and Minimum Heat The TPA2031D1 is a 2.5-W high efficiency filter-free – Efficiency With an 8- Ω Speaker: class-D audio power amplifier in a 1,45 mm × 1,45 – 88% at 400 mW mm wafer chip scale package (WCSP) that requires – 2.8-mA Quiescent Current only three external components. – 0.5- µA Shutdown Current Features like 88% efficiency, –75-dB PSRR, improved RF-rectification immunity, and 8 mm2 total • Only Three External Components PCB area make the TPA2031D1 class-D amp ideal – Optimized PWM Output Stage Eliminates for cellular handsets. 32 ms start-up time allows the LC Output Filter TPA2031D1 to share the same GPIO – Improved PSRR (–75 dB) and Wide Supply enable/shutdown control as the CODEC without Voltage (2.5 V to 5.5 V) Eliminates Need for passing through the CODEC turn-on pop. a Voltage Regulator In cellular handsets, the earpiece, speaker phone, – Fully Differential Design Reduces RF and melody ringer can each be driven by the Rectification and Eliminates Bypass TPA2031D1. The TPA2031D1 allows independent Capacitor gain while summing signals from separate sources, and has a low 36 µV noise floor, A-weighted. – Improved CMRR Eliminates Two Input Coupling Capacitors • Wafer Chip Scale Packaging (WCSP) – NanoFree™ (YZF) 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 NanoFree is a trademark of Texas Instruments.
