This device operates from 2.5 V to 5.5 V, drawing only 1.7 mA of quiescent – Fully Differential Design Reduces RF supply current. The TPA6203A1 is available in the Rectification space-saving 2 mm x 2 mm MicroStar Junior™ BGA – Improved CMRR Eliminates Two Input package, and the space saving 3 mm x 3 mm QFN Coupling Capacitors (DRB) package. – C(BYPASS) Is Optional Due to Fully Differential Features like 85-dB PSRR from 90 Hz to 5 kHz, Design and High PSRR improved RF-rectification immunity, and small PCB • Avaliable in a 2 mm x 2 mm MicroStar area makes the TPA6203A1 ideal for wireless Junior ™ BGA Package (GQV, ZQV) handsets. A fast start-up time of 4 µs with minimal pop makes the TPA6203A1 ideal for PDA • Available in 3 mm x 3 mm QFN Package applications. (DRB) • Available in an 8-Pin PowerPAD™ MSOP (DGN) 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.
