A fast start-up time of Voltage Regulator 1 ms with minimal pop makes the TPA2010D1 – Fully Differential Design Reduces RF (TPA2010) ideal for PDA applications. Rectification and Eliminates Bypass Capacitor In cellular handsets, the earpiece, speaker phone, – Improved CMRR Eliminates Two Input and melody ringer can each be driven by the Coupling Capacitors TPA2010D1. The TPA2010D1 allows independent • Die-size ball grid (DSBGA) gain while summing signals from separate sources and has a low 36 µV noise floor that is A-weighted. – NanoFree™ Lead-Free (YZF) – NanoStar™ SnPb (YEF) Device Information(1) PART NUMBER PACKAGE BODY SIZE (NOM) DSBGA YEF (9) TPA2010D1 1.50 mm × 1.50 mm DSBGA YZF (9) (1) For all available packages, see the Orderable Addendum at the end of the data sheet. 4 TPA2010D1 With Differential Input For A Wireless Phone 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
