This device operates from 2.5 V to 5.5 V, drawing only 1.7 mA of quiescent • Shutdown Current < 10 µA supply current. The TPA6205A1 is available in the • Only Five External Components space-saving 2-mm × 2-mm MicroStar Junior BGA – Improved PSRR (90 dB) and Wide Supply package, and the space saving 3-mm × 3-mm QFN Voltage (2.5 V to 5.5 V) for Direct Battery (DRB) package. Operation Features like 85-dB PSRR from 90 Hz to 5 kHz, – Fully Differential Design Reduces RF improved RF-rectification immunity, and small PCB Rectification area makes the TPA6205A1 ideal for wireless handsets. A fast start-up time of 4s with minimal pop – Improved CMRR Eliminates Two Input makes the TPA6205A1 ideal for PDA applications. Coupling Capacitors – C(BYPASS) Is Optional Due to Fully Differential Device Information(1) Design and High PSRR PART NUMBER PACKAGE BODY SIZE (NOM) • Available in 3-mm × 3-mm QFN Package (DRB) MSOP-PowerPAD (8) 3.00 mm × 3.00 mm • Available in an 8-Pin PowerPAD™ MSOP (DGN) SON (8) 3.00 mm × 3.00 mm TPA6205A1 • Available in a 2-mm × 2-mm MicroStar Junior™ BGA MICROSTAR 2.00 mm × 2.00 mm JUNIOR (8) BGA Package (ZQV) (1) For all available packages, see the orderable addendum at 2 Applications the end of the data sheet. • Designed for Wireless Handsets, PDAs, and Other Mobile Devices • Compatible With Low Power (1.8-V Logic) I/O Threshold Control Signals Application Circuit Example Solution Size 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.
