LC Output Filter Features like 88% efficiency, –75-dB PSRR, – Internally Generated 250-kHz Switching improved RF-rectification immunity, and 8 mm2 total Frequency Eliminates Capacitor and PCB area make the TPA2010D1 (TPA2010) class-D Resistor amp ideal for cellular handsets. A fast start-up time – Improved PSRR (–75 dB) and Wide Supply of 1 ms with minimal pop makes the TPA2010D1 Voltage (2.5 V to 5.5 V) Eliminates Need for (TPA2010) ideal for PDA applications. 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 TPA2010D1. The TPA2010D1 allows independent Capacitor gain while summing signals from seperate sources, and has a low 36 µV noise floor, A-weighted. – Improved CMRR Eliminates Two Input Coupling Capacitors • Wafer Chip Scale Packaging (WCSP) – NanoFree™ Lead-Free (YZF) – NanoStar™ SnPb (YEF) 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.
